- made ds5002fp store internal ram and sfr registers to nvram as they're battery backed
- this includes the 'configuration' details which are actually programmable, so don't belong in the 'MACHINE_CONFIG' section but rather as part of the default NVRAM
- as the exact format of the NVRAM storage is not known, and as not to break compatibility with the 'wrally' set Gaelco offer these bytes are now configured in the ROM LOADING like default NVRAM. Slightly awkward, but probably the best way.
- made the SRAM (external to DS5002FP, but still powered by the same battery) also save content, some games actually use it to store scores etc. as well as the game code.
- cleaned up the Touch and Go Dallas dump, and added some preconfigured internal RAM so that it actually loads the score data from the SRAM properly
- prepared all other drivers for the adding of the SRAM dumps, removing old 'never going to work' simulation code in the process. To do this a wrapper / interface device for the Gaelco Dallas + SRAM box was created.
out of whatsnew
Alligator Hunt was dumped and works, but not yet added, want to verify on a 2nd PCB first as the process does corrupt some bytes and a couple had to be handfixed, so the only way to know for sure is multiple dumps.
http://www.afdelingp.dk/files/articles/ds5002fp/ds5002fp.pdf
namely Touch and Go, World Rally 2, and TH Strikes Back
a 2nd verification pass is still needed on them from additional boards, as bad bits existed in World Rally 2 even prior to extraction (steering logic was broken but bad byte was identified and fixed as the code for that command handler was identical to World Rally 1) and TH Strikes Back is crashing at the first boss (could also be a CPU core issue) Glass was also dumped, but at the time the data wasn't extracted, only the code, and the board has since died, so needs redoing.

Better feedback on cylinder positions. Almost all checks of the winchester test pass (option 16 @ RX50DIAG.TD0 diskette), except low level tests expecting manufacturer or diagnostic tracks (write test #1).
