Well, what a weird year it has been so far.
I’ve been learning to code in VHDL and Verilog on the MiSTer platform.
The first task was one I have wanted to do since I bought an FPGA Replay was to take the existing Bally Arcadia console core, add in the necessary extra ram, pattern board, sparkle circuit and it should be able to run the Arcade astrocade games.
It was no where near as easy as I expected, but after trying to get the timing for the pattern board correct, it finally all works!
Populated the necessary locations for Gorf on the new board, did some sanity checks to make sure I wasn’t putting 5v down any lines to the DE10, discovered a missing track and some layout errors. It all works and I even managed to get the speech working from DDRAM, so you don’t actually need to…
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…
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…
Whilst making recent changes to the Galaxian core on MiSTer, I looked at the newest games in the Mame core as well to see what had been added that runs on standard galaxian hardware. One, that was flagged as ‘Not Working’ was “GuttangT” I didn’t originally plan to look at this any further, but the…
Version 2.3 has been ordered from the PCB makers and will hopefully fix the remaining incorrect track and complete the development of this PCB. I’ve mentioned this on Facebook (on the Gorf group) and had several questions about it, so in an attempt to answer those I have added an information page to the website…
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….
