Minstrel ZX80 Clone

[Shaun_B]

Hi,

I've got an issue two Minstrel clone as well. I've got it set to 4K ROM mode and typed in this listing:

It doesn't seem to work. I see the screen for around .25 seconds and then nothing.

I've checked each array item twice. Is this a known difference?

Regards,

Shaun.

Did you use the loader program to load the machine codes in the list?

There are other notes like "To modify the game to run on USA models of the ZX80 (60 Hz), change the two values coloured red: change '20494' to '14350' and '-12976' to '-13000'. "

Download section "Click here to download 1K ZX80 (4K ROM) Space Invaders reconstruction in .O program format. Run the game using GO TO 100."

It's okay I am a software developer and properly read the instructions so I know about the NTSC bit. I'm in the UK and have a CRT TV to run my ZX80 clone so this shouldn't help.

I typed the program and data in studiously and checked each value in the array at least twice. I've spoken to Paul about this and he has made some non-working fixes. I'll check the array against the emulator .o file tells me.

Thanks,

Shaun.
