MarkB --

Thanks very much for finding the errors (pretty sure I'd found and posted the "1C should be 10" instance, but I don't remember where!). And yes, there should be 8 bytes filled in from 1F8 to 1FF; they are part of the stack that cannot be reliably used by the program. (The cassette tape that shipped with the commercial version of KIM-Venture took care of that.)

I appreciate any effort made on behalf of preserving this program!

Very welcome! I appreciate the effort that went into creating this in the first place!

I haven’t used MAME in a long time, but hopefully some of the others who were trying this game will be able to confirm if this version works ok.

You did, as a comment on the archive.org item for the manual https://archive.org/details/kim-venture-manual

I've had a go at implementing the fixes from MarkB (8 bytes of 00, 1C->10) and while it loads fine into MAME, the LCDs just turn off and don't turn back on again

Try again after this commit https://github.com/mamedev/mame/commit/2d111b15929a39084bb5875dedec8ffea301dcf0
I think i 'unintentionally' fixed this black screen problem with Kim-Venture when I added PWM_DISPLAY device to this driver.
