8kB RAM Adapter for the Sega SG-1000 implemenation

Forgot to put the issues on the github as well as the forum

While browsing my library of SG-1000 games, I noticed many Tawainese only games and I wanted to try them out, they are all in a non working states on Bizhawk (and also on Kega Fusion). All the games boot with the Dahjee or Jumbo Logo and reset in a loop.

I highly doubt that it will be a priority to implement that adapter for bizhawk, or if there is even documentation about the special adapter and the games, but it allow you to play a bunch of SG-1000 games. According to the reference, these are all pirated games.

List of games using that feature

• Bomberman Special (there is also another pirate release of that game that work with Bizhawk)
• The Castle (There is also a regular Sega release that work with Bizhawk)
• Knightmare
• The Legend of Kage
• Magical Kid Wiz
• Pippols
• Rally-X
• Road Fighter
• Star Soldier
• Tank Battalion
• TwinBee
• Yie Ar Kung-Fu II
• Zanac

Start with the 8kB RAM Adapter reference linked in the issue and reproduce the reset loop with one of the listed SG-1000 games. Locate BizHawk’s SG-1000 emulation entry point and determine the adapter behavior needed; done means the affected games boot and run without regressions.
