Commander X16

Oh, is that the one that I reacted to? Yeah, that's a good one.

We'll consider adding .prg to the executable file, if that's a convention on the Commander X16. It has arisen somewhat organically; to the X16, all files residing on the SD card are of type PRG (unless they're directories), so you can't tell which files are intended to be executable and which files...

I have actually just redesigned the PCB to make it a lot smaller. I was thinking about adding PCB mounted plugs for both the DB9 and the SNES controller. The issue is that if I add normal PCB mounted SNES connectors, I would need a cable with the same type of plug in both ends and I can not find th...

When you call a machine language routine in assembly, you simply load the necessary values in the registers and perform a JSR to the address of the routine. LDA #$65 ;load accumulator with value $65 JSR $FFD2 ;jump-subroutine to CHROUT ($FFD2) When you do this from BASIC, you have no way to access t...

Just as back in the day, there was software that required more than the standard RAM size, there's no reason that shouldn't exist now. You wanna run with the big dogs, then you need more byte. This may or may not be possible with console systems. David has said that it's probably a good idea to tar...

Since the upper significant byte of the address for all the IO spaces is $9F, it looks like your hardware is picking up that upper address byte (A8-A15) instead of the actual D0-D7 lines. Double-check your signal routing on the PCB, and the card slot pinout?

If that were the case, hitting RESET on the X16 would fix it, wouldn't it?

That manually-played version, would that be this? https://www.youtube.com/watch?v=RbdpBwxAC5w

If the coordinates are reversed, shouldn't ROW and COLUMN be reversed?

They are. $030D is the X register; $030E is the Y register.
