The problem with the high score saving for Gorf and Wizard of Wor should now be resolved.
You can now see the settings menu when the OSD button is pressed, although background will be black or just stars, which allows you to change the settings once more.
Reloading the scores will no longer cause other unwanted side effects.
I did some more testing and changes on the MiSTer -> Astrocade interface and have made some changes. Main PCB now includes a ‘Menu’ button to bring up the main OSD. The third speech only channel has been added for Wizard of Wor and I fixed the missing track from V2. The RGB board has…
The MiSTer core for Cosmic Guerilla has been completed. This core uses a TMS9900 CPU where the original uses a TMS9980 (8 bit version of same CPU, just does 2 byte reads/writes instead of 1 word read/write). However, game speed is controlled using vertical counter, so should be the same as the original. Sound effects…
I have added two new images to the “Putting it Together” page (here) that now implement the NVRam that could be used with the hardware. The games that support this are “Gorf” and “Wizard of Wor”. These versions will allow you to save the high scores to the SDRam card whenever they change. To do…
I have removed the downloads for the images with High Score saving for the moment as I have found a couple of problems during further testing. They will be back when I sort out these problems!
The new version of the RGB PCB has arrived, along with the updated design for the composite output for Space Zap and I have assembled one and connected it up to my Amiga monitor. It now has potentiometers to allow the signal levels for Sync and Video to be adjusted to work nicely with your…
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.
