I've recently acquired a PCB version of Truxton, but have an issue with saving high scores. Just wondered whether anybody knows whether the board has a battery back-up, or whether its simply a case of taking a digital pic for proof of success (or failure) .
Naturally, one would check to see if such a Ni-Cad or lithium-based battery is actually installed on the arcade PCB. If there isn't one, then the arcade PCB in question would not be able to save such high scores upon powering down for the night. ^_~
There are some arcade Jamma PCBs that have back-up battery to save high scores for posterity such as:
Seibu Kaihatsu's Raiden II (some Raiden II PCBs never had such a "back-up" battery installed in the first place...so bye-bye high scores when turned off...it is recommended that if you want a Raiden II PCB, get one with a "Back-up" battery installed. If it is dead, then a replacement would be needed & you're back in business -- "high score-wise".) ^_~
Seibu Kaihatsu's Raiden DX (again, some Raiden DX PCBs never had such "Back-up" battery installed in the first place)
Seibu Kaihatsu's SP1 mobo (per SP1 game cart loaded up into the RAM banks)
Sega ST-V Titan mobo with CR-2032 "coin-type" button cell battery (for high scores and game settings saves as well).
You'd even be suprised to learn that some Atari Games produced Jamma PCBs can save high scores without the need for such a "back-up" battery such as:
Atari Games' 1990 Klax PCB (has the biggest on-board capacitor I've ever seen on an arcade Jamma PCB to save such high scores & game settings...but it works, just don't ask me how.) ^_~
Atari Games' 1991 "Off the Wall" PCB

Thanks for the input PC Engine Fan. There's certainly no sign of lithium ion or nickel cadmium on the board Wasn't sure whether the scores could be saved to RAM or SDRAM, or some other inconspicuous looking chip.
