Back in 2011 I started a tutorial series on how to create a C64 game in several steps. This was originally posted on Retro Remakes, GameDev.Net and Forum64. Since then several updates partially broke the posted series and so I've decided to host it on my own homepage.

This series ran for 100 steps until 2013 and created a full game, which later became Guns'n'Ghosts.

Go here to start the journey!

Tuck's Adventures on Meta is a remake of a DOS game I made almost 30 years ago.

It is kind of a Metroidvania, you find items which provide access to new areas, or new abilities. There are no enemies, but lots of holes to fall into :)

Tuck is on his way to Vokuhilon to the big snail farm auction. But unfortunately the engine fails and he has to emergency land on Meta. Stranded he now has to find a space ship repair kit (a very rare item!). Help Tuck find his way about and fix up his space ship in time!

Get 'em Good is a remake of a C64 game called Get 'em DX. It's a mixture of Pacman, a shooter and strategic extra usage.
Clear every screen of all dots. Be sure to fight back enemies, as they drop nice extras. Pickup 9 of a kind to activate a particular powerup. Once all dots are collected grab the key and unlock the exit!
Careful though, the enemies will get faster and tougher as the stages advance. So you have to be on your toes and be sure to grab enough powerups to keep up with them.

Randomized stages allow for high replayability as no two games are alike! Play alone or team up. Both players play with one score and one pool of lives. The one who activates an powerup is the only one to receive it though.

Iron Willy is a commercial advertisign game from 1997. It was written for the DVS - Deutscher Verband für Schweißen und verwandte Verfahren e.V. (http://www.die-verbindungs-spezialisten.de via the DVS Media GmbH.

This DOS game is one of my favourite projects and was created with several great gals and guys and lots of love. As a bonus the speech is fully functional! Due to the market back then it's only available in german though.

This packet is available for download with kind permission of the DVS Media GmbH.

The download contains the DOS emulator DOS-Box, to start the game simply double click the batch file "Iron Willy.bat".

The game itself is an adventure in 3 acts, an pure adventure part, a puzzle part with lots of welding and a short action part near the end.

Ok Comrades,

It seems Mother Russia is falling behind in the arcade stakes. So this must be rectified immediately. So I have had a note from a Mr V. Putin saying he needs your input.

Now being Russia they dont want flashy graphics and that ... See Tetris none of that high resolution stuff.

Make Russia great again with such games as Tsar Wars, Hunt for Pink Oktober and such other great games...


Thus the comrades from Retro Remakes let us know, and I followed their call.

I'm currently playing every single set and see if it's solvable. You may notice that some sets had updates in November, some in January. I'm about half way through, so expect a few more updates sets.

And unfortunately a few new bug fixes:

Major one: I re-added a few known behaviour bugs, which some user level sets relied upon. Now all sets should be solvable again.
Once you win a set you should no be able to return to the main menu.
No more crashes in levels with many objects.
Speedup for levels with many objects
Speedup for the level selection screen, huge levels caused quite a slowdown for the preview.

With the proper short cut keys the game difficulty can be changed while playing, makes beating those nasty stages easier.

Some user levels were unsolvable, because they either used accidental features which I fixed; or they really were broken. These features are restored (like moving boxes over one way blocks), other stages have been adjusted.

Nobody should feel forced to anything. Still, there are some costs for hosting the site and also creating new games. If you want to support new development, I'd be really happy and thankful.

And don't worry, everything is and will stay free!



In other news HitBlock is perfectly stable. The last touches are set to new stages, a few new features and most of all, compatibility to older stages. All existing stages from the online level database will work fine!

Add: Add item to project asks for filename upfront
Fix: Pasting image in graphic editor does not check for validity
Add: Binary editor (File->New->Binary Editor)
Fix: Deleting live breakpoints while in broken state might delete wrong breakpoint
Add: Better PDS assembler support, DH, DL, CBM, EQU, proper local labels
Fix: Major speedup on longer warning/error list
Fix: Media Manager: Rewrote file handling (load address was getting messed up again)
Fix: Assembler type auto detect now really working

And the work never ends: HitBlock' GUI is technically done but there's lots of gameplay TODOs left.
Esp. stages for the new game modes. And I want to double check with older level sets so they're still solvable.
Plus the levels with the tight gap should get playable again.

Fix: Read Only displays (Output) are now really read only
Fix: Search All had off by one line numbers
Fix: Replace all could run into endless loops if the replaced text contained the search text
Add: Search All now brings search result list to foreground
Add: Search All now shows proper line numbers for currently closed documents
Add: Debugger now jumps to disassembly if cpu pointer is not in code

Und Ludum Dare #27!

The theme: 10 seconds

The magic apocalypse happened. A magic rift is tearing the world apart in ten seconds. The only way to avoid this
is to get to the magic source and repair it. But you've only got 10 seconds...

Human Roundup was written for a little inofficial competition at Gamedev.Net.

What if dinosaurs weren't extinct?

Then they would herd humans! Drive your herd into their designated goals :)

Fix: Saving element outside project path doesn't crash anymore
Fix: Complete rebuild of BASIC tokenizer according to C64 kernal
Add: Support for store/load/exec breakpoint types
Add: Focus now shifts to Emulator/IDE during debugging depending on state
Add: Find/Replace dialog of Scintilla replaced by self built dialog, now allows search in file and properly holds search/replace history (may be buggy)
Add: Button to force hires/multicolor on all characters in Charset Editor

Nothing spectacular this round, but it's an update!

HitBlock is going strong GUI wise, and a lot of testing is required now. There are still quite a few bugs hidden away.

In a short time a new puzzle game should be available. I had planned it for this update but I just wasn't satisfied with the overall look.

As promised here's the first of the more regular updates.

Currently I'm working on HitBlock Deluxe for PC and Hyperion for C64.

Since I'm also working over the uploaded level database I'd be happy to hear your thoughts. A new feature will be a download count. Maybe also level voting but only if I can keep misuse down.

Hyperion will be a metroid like game with scrolling, lots of aliens and a dark background story. To see a few mockups head over to Lemon64.

Add: Build Macros ConfigName and ProjectPath
Add: Command line tool MediaManager
Add: Renaming files in File Manager
Add: !for macro
Add: !macro macro
Fix: Disassembler would abort if jumps were out of bounds, relative addresses were calculated wrong
Fix: lo/hi-byte operator now works properly also inside an expression
Fix: Exception when !source-ing empty file
Fix: Adding Watch of local label now works

Breaking Change:
Fixing the lo/hi-byte operator now makes expression like # In case of doubt add paranthesis! #<( buff + $20 ) or !byte <( a + b )

The provider change is done, the site has moved.

Now the recurring outages and being-hacked should be a thing of the past.

Plus: There will be more and more regular updates. Not every single one will have a download though :)

HitBlock is making good progress however it won't be done by end of this year.

On the other hand another C64 project is done, Get ´em DX. It's a polished version of the original game from 2011. This time with spruced up graphics and real music and sound effects.

A free download and also buyable media versions for fans and lovers of good old games can be found here or at RGCD.

A bunch of new features and bug fixes result in C64Studio 2.4:

23.09.2012 - 2.4:

Changed ASM parser, now checks for * inside !IF work
Fixed saving of charset export file name
Proper behaviour for files saved outside of project folder
Enabled watches for ,x and ,y (needs to be selected)
Fixed Basic bugs: * was resulting in @, PRINTX was not recognized as PRINT
Fixed asm bugs: 3 digit hex numbers were treates as single byte
Fixed crash for properties of new Basic files that were not saved yet
Syntax Coloring customizable (in certain limits)
Grid in sprite/charset editor
Copy/Paste in sprite/charset editor now doesn't care about image size
PETSCII character table

It's way too long without an entry.

On 1st of July Soulless for C64 was released. It can actually bought in two web shops as tape, disk, cartridge or digital download. Poster and companion CD are available as well. Take a look at Psytronik or RGCD :)


Also, since it was asked for in the guest book, find a very very work in progress of a 3d puzzle game over here.

10th anniversary of Ludum Dare!

A little rogue like. Fight monsters, earn experience, grow stronger to finally beat the mighty beast.

Find the game here.

Finally a new entry. Children need a lot of time :)

It's a little simple christmas game for the smaller. Santa brought a few presents to the wrong houses and Rudolph has to sort it out. Land carefully and deliver presents to their rightful owner.

You can't really crash, but lose a lot of reindeers.

Find the game here.

Merry christmas too all out there!

And Ludum Dare struck again!

This time #20 with the theme "It's dangerous to go alone, take this!"

Not really innovative a little Zelda clone was created. The game is rather short, as consolidation there's an editor and even some enemies.

Find the game here.

To get things going again:

An unfinished 3d pacman game. Get the game here.

Christmas is nearly there, the super markets are preparing for Easter. Christmas is in the air.

Here's a little present. Not a real game, just a small fun toy. Decorate the tree! Listen to the music! And torch the decoration.

Find the toy here.

That extra brain food!

A little bit older, fixed up and made ready. It's a funny little puzzle game with editor. To download go this way.

And yet again distracted by a challenge!

This time it's a complete game, rather short though.

Imagine a 3d world, folded into a plane. And now, fold at a different spot. This makes it possible to access all kinds of short cuts. Difficult to describe, just give it a try, right here.

A long long time ago I tried to start the experiment experiment. It worked for one entry :)

To get things going again here's the download to an older experiment, Gyroscope Plus.

To get the download and more info go here.

And finally a new game. For the C64.

This was my entry for the Forum64 Basic competition. It's a little Final Fantasy clone and might even be fun to play!

Get the game here.

I couldn't resist again: GDC 3h VII.
Write a game to a specific theme in 3 hours. This time a puzzle game with the theme "spring". Result is a nice little game that even is not completely easy!

In other news HitBlock Deluxe is progressing quite well.

Find the game here.

A little late for valentine's day, a little game inspired by Night Shift.

Earn money in the chocolate heart factory. Maintain the big machine, keep it going and produce the required number of packaged chocolate hearts. Jump back and forth and repair the broken parts which mess up the production.

Find the game here.

And finally a real update!

I couldn't resist participating in yet another programming competition. The result is a fine little game over here.

Sorry guys, still not the finished version of Deluxe.

While toying with Windows 7 I noticed that the setup doesn't work right. I've worked it over and it should do its job now.

Find the new Setup here.

Alas, this is not yet the new bigger better version. Since a magazine asked I've upgraded the old code base for HitBlock Final.

This version doesn't ship with all sets predownloaded, it works fine with Vista (and probably Windows 7) and also received a few bugfixes.

Due to the changes this version can not be installed as update of a previous HitBlock installation.

More about it here.

It's been quite some time since the last update!

After moving house I plan to speed up development again. Let's start with a sad little excuse for a game, once more for Ludum Dare!

Find more about it here.

And now to something completely different:

Since my interest in C# and also SilverLight I participated in yet another programming competition. The following game resulted.

Requires SilverLight 2, a browser plugin based on .NET, available for common browsers and OSes.


So hurry up into the SilverLight department!

I've gotten sidetracked by various projects as usual. A lot has been touched and tested. One result

Ludum Dare #14: Doom Runner

More over here.

Since i borked it last time the download link for XOrbit is now available.

A little update for HitBlock Deluxe.

The cooperative 2 player mode is working, the whole GUI stuff is missing ;)

And part 2 of the experiment experiment:

XOrbit. Since its WIP it's pretty rough around the edges. Try the "Nasty Puzzle" mode for a little hectic.

More about it here.

Hi there,

While cleaning up behind the old stuff box in the cellar i found a few gems under heaps of dust. For one, there's my first version of HitBlock for DOS, as well as a few other old games, now conveniently sorted in Other Programs.

In other news the work on HitBlock Deluxe is commencing nicely. I'm getting in the working mood again.

Have fun!

Finally Joe Gunn is out for sale!

For lovers of the good old breadbin: Joe Gunn is available on tape. The game is the same, there is a little extra for buyers included though.

The shop is here.

The game is still available as emulator file for free over here.
