@davepl1968 Compiled without issue on a RPi that is connected to this 1982 Hazeltine Esprit III terminal 🤩

@benheck new release on github ... there is a define in main.c for loop delay if it is now too fast. :)

a PC port of @benheck's Catskillvania originally written for the #midwestgamingclassic #gamebadge. Still a WIP ... no sound yet ... yo Bud!

[Johannes Le Roux @dadecoza]

@benheck I'm amazed at the amount of detail you added into the game ... those shakes, explosions, and animations too cool to be limited to the Pico. 😀

[Johannes Le Roux @dadecoza]

@benheck I'm glad you tried it! as for the speed I'm at the mercy of GTKs "tick rate" but let me see if there is a way to increase it.

[Johannes Le Roux @dadecoza]

@benheck I think everything is now working ... successfully compiled under Windows, macOS, and Linux ... even tested on a Pocket CHIP ... https://t.co/UtUSdNhr5A

[Johannes Le Roux @dadecoza]

@benheck I did notice that and since I'm just pumping pixels directly into memory I had to remove it. oh and I must commend you for writing such well commented code!

[Johannes Le Roux @dadecoza]

@benheck here is a JavaScript port of your game with some inconsistent and regrettable AI generated game art ... https://t.co/r22lRB1bYs

Now that @Logiker464 's Vintage Computing Challenge 2023 concluded, I can share my code. There were over 200 entries with the average code size of 80Bytes, the winning code was a mere 23Bytes! and my entry 54Bytes. #vccc2023 #zx81 #z80

@VoxTelecom Kraaifontein area: There was an Octotel network drop, and other ISPs were able to recover automatically but Vox clients are still down. The PPPOE connections keeps on retrying. Please help ... it is over an hour now.

@8BitShowAndTell Inspired by your Compumate video I were again motivated to try and use an Atari 2600 as a standalone computer ... so here is a machine language monitor on the Atari 2600 printing "hello world" . at the end I write to the TIA background color register.
