DOA1 Model 2 Arcade - Unlock RAIDOU

[grap3fruitman]

Running the machine for at least 25 days will unlock Raidou in the original arcade Dead or Alive.

(character select)

Total runtime is stored in ram at 0x01d00000, which gets compared to value 0x20f57f (2,159,999 seconds) and sets flag 0x54fd76 to true when the counter is greater, unlocking Raidou. (0x54fd56 in doaa, doaab, doaae, doab)

(machine code with notes)

(bookkeeping screen)

Here's a Mame code to skip the wait and simply set the flag.

Forgive me for any typos. Typed these up on a mobile device since the utility company knocked out the internet a few days ago. I was too excited not to share.

If I'm reading the assembly correctly, Raidou simply unlocks after the "Total Time" counter reaches 25 days.
Can anyone test on hardware?

So damn cool!!!

The only downside is that because P1 and P2 cursors starts at Kasumi and Jann Lee, this will look very awkward when starting the game after unlocking Raidou. Are you able to move Raidou's slot to a different location, maybe between Kasumi and Jann Lee or on the top row, maybe after Tina or between Bayman and Lei-Fang?
