Sega X-Board Hardware Memory Test

Sega X-Board Memory Test Software

A set of ROM images to test the RAM ICs and custom chips on Sega X-Board hardware (AfterBurner, Thunderblade etc.). It is more robust than the on-board tests and stands a better chance of running on a dead boardset.

• It does not require working main RAM to actually run the main RAM test.
• Remove all sub CPU EPROMs when installing (IC 20, IC 29 etc), as these interfere with the results.
• It requires a vanilla 68K CPU to be installed, not the FD1094 security processor present on some X-Board games.
• The palette will be incorrect when used on games other than AfterBurner. But it should still operate correctly.

This was not previously released, because I hadn't verified the IC labeling on hardware. However, a number of people have already used this software to successfully fix PCBs. Therefore, I figured I should get this out there and address problems as they are reported.

This is based on the OutRun Memory Test.
