Re: [MAME] Emulating the MTX

The SDDISC.BIN file from Andy Key's rememotech distribution is where I started for the prototype CFX's CF image. What's the difference between sddisc.bin and sddisc2.bin? They both seem to work, can boot into CP/M and load MTX and RUN files. 0008.png Think I'll take a look at the MAGROM next. I'm s...

Re: [MAME] Emulating the MTX

I've added emulation of the CFX system to MAME:

Any chance of an image of the CF card that's usually supplied with the actual device?

Re: [MAME] Emulating the MTX

MAME now supports loading software from WAVs, and the majority of games from http://www.mtxworld.dk/download.php are working. There are a couple that hang after loading, namely Pac-Man and Zombie Near. With Pac-man it loads, decodes, fills screen with game font/text/chars then gets stuck in an infin...

Re: System test rom/Board

It looks line Mame might be initialising the video ram to zero. Correct, well it doesn't randomise it first. The real MTX can have junk in there on boot, so my emulator doesn't bother to clear it. The test rom didn't either, so I'm getting junk on the display for codes less than 32. Thanks for expl...

Re: System test rom/Board

Thanks for posting the ROM image.

Curiously I'm getting slightly different output from the ROM test for ROM1 in MAME, any ideas why?

I'm assuming your screenshots are from an emulator, so what does a real MTX show?

Re: System test rom/Board

Would really like to run your diagnostics ROM in MAME sometime, to convince myself the RAM banking and MTX500 is correct.

Re: [MAME] Emulating the MTX

I thought that I would have dumped the SDX 80 column card ROMs, but it appears not. I will do it next week. Any movement on this? I'm also looking for any original SDX ROM dumps, not remakes as used in MEMU. The only one I can be sure of is the CP/M ROM from http://www.primrosebank.net/computers/mt...

Re: [MAME] Emulating the MTX

F: is usually a RAM disk not a Silicon Disk. It uses the pages above 64K on the MTX. Of course, the clue was in my previous screenshot "F: is type 51 - 512Kb RAM disc". Managed to format F:, copy over the SDX System Disk, and run NewWord from it, so looks good. So how do I configure the S...

Re: [MAME] Emulating the MTX

I thought that I would have dumped the SDX 80 column card ROMs, but it appears not. I will do it next week. Thanks, that would be really useful. You could just copy files to and from the RAM disk to test it? But I need to format it first. Looks like multiple formatters on the SDX CP/M System Disk, ...

Re: [MAME] Emulating the MTX

Finally got around to taking another look at implementing the SDX in MAME. It seems I was a little hasty in giving up, once I set the dipswitches correctly it booted into CP/M. These are using SDXCPM ROM, with the original CP/M System Disc in IMD format: sdxcpm.png cpmbbc.png I see that MEMU uses fa...
