What is the max VPP voltage?

Sorry, I ended up returning it, as rather than myself, I had a local place program car ECU than myself.

Can i use to make snes, nes and n64 roms?

You can use this to program snes and nes eproms (using the 27c line of eproms), but not n64.

Can this program single-shot proms in addition to eproms?

Yes, OTP devices can be programmed. I suggest perusing the supported device list to see if your required device is listed.

Does this work with Windows XP 32-bit?

The drivers and main program does work on 32-bit XP
