I'll have a look if I can automate the whole thing once I've got my own multi...

If you go into this with the right mindset, that you're buying a (probably good) repro, then there is nothing wrong with this. Maybe the price goes down a bit once all the rich collectors have one, then again, they may run out of components.

My NBM arrived, and I was able to test this with the UniBIOS, and the game reports itself as 4 player version: So far I've been unable to test an actual 4 player game, though... The best I get is 2 players against 2 AI, with one player playing the main char and the other the tag buddy on the...

Though there was a time when custom PCBs were unaffordable without a significant investment, or making very small numbers etching them yourself. There are now things like https://tinytapeout.com/ , and there are companies that can turn your working FPGA design into an ASIC for something like...

1 please!

I'm getting 403 forbidden for the image.

Someone already started to port mister to a larger FPGA, it is only a matter of time for the DE-10 to be replaced with something more powerful.

These things always depend on someone to sit down and say "I want this to happen". I have no idea how different the SH-3 is, but there is a Saturn core making good progress. The FPGA seems to work mostly as a Blitter, so reimplementing this shouldn't be rocket surgery. The tricky bit will be to...

The FPGA is obsolete as well: https://www.digikey.de/short/5b19dh4p In short, I think it is more likely that someone will invest the time into a Mister (or Mister successor) core than making a reasonably priced clone of the PCB. You not only need to invest the time to make the PCB, but acquire a...

What kind of FPGA is on there? If that is not available you won't be able to upload the bitstream, either. Also I have no idea if that is encrypted/protected in any way. Someone doing stuff like https://www.tindie.com/stores/bobsbits/ for Retro computers posted pictures, they sand off the...

No idea, I didn't have any luck finding the thread, and I don't remember if it was an embedded image or a link to a blog. They basically desoldered the TSOP flash chips and put connectors for flat-flex on the pin rows, which then went to a custom PCB. Maybe I'm mixing that up with another...

I expect you can do most early boards up to the point where budgets were high enough for custom ASICs or Gate Arrays. Then you can do bootlegs for a while, or hope to use customs from corroded/damaged PCBs.

I seem to remember a thread here, with pictures where someone connected ribbon cables to the flash footprints, followed by "they stopped when CAVE asked them to".

Didn't the last person trying to make a multi for CV1K get a strongly worded letter from CAVE?

Would one of these work? https://www.renesas.com/us/en/products/microcontrollers-microprocessors/other-mcus-mpus/superh-risc-engine-family-mcus/sh7709s-32-bit-microcontrollers
