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...

Happy to hear that so many C64 fans are enjoying Paul's amazing port of Spelunky Classic! 🔗 paulko64.itch.io/spelunky64

Spelunky64 by PaulKo64

Official Commodore 64 port of the classic roguelike platformer.

Unbelievable, thank you all! 😍

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 😀

Title sequence for my new #c64 game implemented!

"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...

Found this nice site for people getting back into #C64 gaming. It even mentions 3 of my own games 😀 retrogamestart.com/answers/get-...

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

Thanks @retro-gamer.de for the nice words on #Spelunky64 😀

It looks like there is a review of #Spelunky64 in the latest German edition of Retro Gamer. I need to get me a copy. 😀

Das erwartet euch in Retro Gamer 2/25 🤩 Das Heft gibt's im Handel oder auf der Retro-Gamer-Website.

A little video I put together for "Spelunky 64" on the #C64 , a great New Wave release . Check out my full review & developer interview below 👇 youtu.be/ck5DDAJqDw8?...

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:

So what is your favorite item in #Spelunky64 ?

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