yep, it's a different scene, and the NEXT is well suited to arcade conversions using the original code for game logic but which reinterpret the video / sound. In cases like that emulation helps greatly.

not a bad product, but supply issues will likely condemn the hardware to being not much more than a historical footnote.

Pretty much all of these "modern retro systems" lean heavily on emulators existing to make software easier/possible.

I would call it FPGA "translation", not emulation. Trying to use original FPGA "language" as close as possible but unfortunately have to take shortcuts sometimes.
Not sure about whole varaity of peripherals - current goal is implement Next specific features whatever others Spectrums in MAME can't provide now.

It shouldn't be hard to beat other emulators wink

Nice. I was talking to some of the people involved with this last year, and despite it being a recent system, it's an open design and they're happy to see it emulated as emulation helps with development of new software etc.

It'll be interesting to see if MAME compatibility ends up better than the other emulators, as while we're not emulating it at an FPGA level, we are a lot more flexible and emulate more of the extra peripherals.

Interesting use of a limited display. Nice

You might enjoy seeing a demonstration: Dominic Bumbaca played it on a KIM-1 and recorded it for YouTube at

How to start this game from MAME's swlist (RB asked):

mame kim1 kimvent

There are brief instructions in the hash file:
Enter 'R -00F1=00 -17F9=A1 -1873X'. Play tape, pause when display shows 0000 (P). '-17F9=A2 -1873X', (P), '-17F9=A3 -1873X', (P), '-0100X'.
I'll make them more verbose:

Either type (pc keys) or do a MAME UI paste (shift+scrlock by default):
R -00F1=00 -17F9=A1 -1873X
(00F1 is for configuring decimal mode, 17F9 is for entering the tape file ID, 1873 is for loading)
Play the tape from beginning, and when display shows "0000 xx", pause the tape before the next segment starts. The tape won't pause automatically when the segment has finished loading.

Type/paste: -17F9=A2 -1873X
Unpause the tape, and when display shows "0000 xx", pause the tape before the next segment starts.

Type/paste: -17F9=A3 -1873X
Unpause the tape, and when display shows "0000 xx", pause the tape before the next segment starts (latter isn't really needed since this is the last segment of the main program)

Type/paste: -0100X
The game starts.

Pausing the tape all the time is annoying. Since it looks for the unique ID to load, it's not really necessary to do this. You can simply rewind the tape before loading the next segment, and hold INS to fastforward MAME until you see "0000 xx".

Re: Running Doom in DOS BIOS-D 12/03/23 09:47 AM
All this time I've been testing with default settings in a clean folder except for ROM locations. So far I've tested all the way back to 0.181 and the result is constantly the same. Yet, I've found out something that could be useful. Any of the MS-DOS disks listed above boot on ct486 when you press any key every two or so seconds while the disk is booting. If you do not the system hangs into an infinite loop for every MAME version so far. I'll try to test more older MAME versions and see if I find something else.
