The first LED from the right is telling the ROR is missing, the second the jump page bug is there, the third is telling it is NMOS.
Nice to see my white 6502 CPU is OK, and is indeed missing the ROR instruction.

I now have a working "loader" for the "AMAZE!!!" #kim1 game.

It starts, shows something on the display, waits for a selection from the keypad, copies the selected maze data (only one for now, need to design a few more) in the appropriate memory zone, then hands the control over the tape load routine in the monitor.

The "player" can then push play on the tape reader and allow the main game to load.

The end result sits in a single audio file with the two programs.

BTW, before today I never used dosbox in a makefile.

I've added the audio file you can use to load the game via tape.

Tested it on MAME for now, but I expect it to work on the real thing.

I actually took the time to type in the whole program on my #KIM1 clone, and it worked!

So, I've decided to release it for everyone: https://codeberg.org/hkzlab/AMaze_KIM-1

I've called it "AMAZE!!!".

It's currently raw binary only. I plan to look into a tape conversion. Once done (and tested) I'll release that also.

Hell, I'm also tempted to release this on itch.io just for shit and giggles. Like, maybe if you pay me 1€ I'll provide the pre-drawn map of the labyrinth to you in addition to the free game.

You save in pencils and papers. It's the greatest deal.

As usual ☕ on ko-fi if you think it's worth I spend my time doing these absurdities
