I managed to complete another core for the MiSTer today, been a while as I needed to get the two PCB’s working enough to sample the sounds. But all of the games from Mame’s Universal Cosmic driver that use a Z80 are now on there. Cosmic Alien, Devil Zone, Magical Spot, No Mans Land and Space Panic. (All with sound, unlike Mame which only has it in Cosmic Alien and Space Panic)
I’ve updated the bill of materials for the Astrocade interface a little. Two items have been changed to have better descriptions and where people have let me know part numbers from Mouser or Digikey I have added them on.
Version 2.3 of the PCB has arrived, been assembled and tested … and it works without any wire patches! There is, however, one minor problem. I added some extra bits of screen print on the wrong side. This has now been fixed on the gerbers and any future boards will be correct, but I am…
The MiSTer image for Gorf using the Astrocade interface has been updated. For those of you running them in an arcade environment where customers have to put money in, it will now accept coins from both coin slots (with separate options in the DIP settings) In addition, the SLAM will now work, so if someone…
I thought that swopping the CPU in the cosmic core to allow me to do Cosmic Guerilla would be simple. How wrong was I … 16 bit vs 8 bit, different memory read write signals, different port handling, even the reset is different! Anyway, for the first time it actually shows something running on screen….
Following on from Astrocade hardware, I thought I would like to do a core as near as possible from scratch. So apart from using the Z80 from opencores, and basing the timing code on that used in the Pacman core, I went from the Crazy Balloon schematics to produce a complete core for it. Where…
I know it looks the same as the pictures from the Multigame connected to a galaxian PCB, but this time I updated the Galaxian core on the MiSTer to allow me to run the multigame on it. It should make testing things a lot quicker since the MiSTer is always connected and ready to go….
