Robotron, Joust, and Defender are some of the most memorable and classic of arcade games. These were all developed by Williams Electronics in the early 80s using the 6809 cpu. Obsidian recently brought these FPGA implementations to the Pocket. There are 3 different cores covering the slightly different chipsets. These cores have been collected into a single combination core.
Alternate versions and Rom hacks have been included when available. You can find those in the _alternatives directory.
As with the other pocket-extra cores, I'm not including any RBF core files. Please source them yourself from Obsidian's distributions.
Check inside the following location to see which RBF files are required:
- /Cores/obsidian.Williams6809/
MRAs are included for the new alternatives. You can either build the roms yourself, or they should also be available via your favorite updaters.
