While the #c64 port has been available for free for years, this week you can also get the original for free!

Some 15 (!) years ago I worked on my own version of a #c64 AGI interpreter. I was able to run several KQ1 rooms before I lost interest due to the enormity of the task. Apparently Mean Hamster Software succeeded in keeping motivation high: meanhamster.com/games/agi-64

Was working on implementing a heart/health system in my latest #C64 game. With a player death check not yet implemented, my routine was happy to spit out 255 hearts 😀. #gamedev

I'm still using the exact same #C64 Programmers Reference Guide that my late father bought some 40 years ago for 59 Dutch guilders! It even still contains some of his handwritten notes...

One of the missing features from #Spelunky64, the ability to push blocks, is now included in my new #c64 game 😀

Received this nice #c64 themed card at work today, because apparently my official work contract started 12,5 years ago 😀

"one of the games on this list is an "impossible" port I never, ever thought I'd see running on a real C64. My jaw is still on the floor, and I'm on my knees collecting my teeth writing it all with one hand." 😀 www.youtube.com/watch?v=0WkN...

Sorry for the lack of updates on my #c64 #gamedev recently. However, this doesn't mean there is no progress. Working on an original concept means some ideas just don't work out as intended and need to be scrapped again, slowing progress somewhat...

Amazing #Spelunky64 playthrough with some narrowing escapes. Too bad my Finnish is not very good 😀 www.youtube.com/watch?v=CzFc...

Implemented player "eye blinking idle animation". Although it only changes two pixels for a few frames, it makes all the difference! 😀

For my new #c64 game I'm again going for a "single-button multi-purpose" control scheme. I was quite happy with how this turned out in #Spelunky64 :)

Happy Monday, #GameDev crew! Nestled on my bookshelf is this treasure from #Spelunky dev Derek Yu ( @mossmouth.bsky.social ), published in 2016 by Boss Fight Books ( @bossfightbooks.com ). A short thread 🧵 about why I love this book and reference it often:

Image of a book on a table. The book is “Spelunky,” by Derek Yu, published in 2018 by Boss Fight Books. The cover features an image of an eggplant. Very mysterious!

Screenshot of the PC version of Spelunky, with its original pixel art. Our cave explorer hero is jumping around a procedurally generated level. A damsel is awaiting rescue in the corner, while bats and snakes lurk below…

Decided to change from discrete to full physics movement for my new #c64 project. This makes it a lot smoother looking already 😀
