new NOT WORKING clones

Go Retro Portable 250+ Games (US, V1.3) [Sean Riddle, David Haywood]
Go Retro Portable 250+ Games (US, V1.2) [Sean Riddle, David Haywood]

these licensed devices are protected like the other 2 sets (~0x100 bytes of code read from mystery device)

  • simulated protection for lxcap, tetrtin, pactin rather than bypassing it
  • also hooked up lxcap protection device to otrail, which boots with it present
  • hooked it up to mog_m320 and pixel246, the former of which now goes to menu (pixel246 seems to ignore the results anyway)
  • hooked up seeprom to otrail, allowing for game to be loaded / saved and high score table to show correctly
  • various cleanups (ATTR_COLD, formatting)
