Flash isn't the exact word.
Most arcade games use EPROMS. ERASABLE programmable, read only memory. Some only used PROMS (this is rare), which is just PROGRAMMABLE, Read only memory (without the eraseable part).
Basically it goes like this. Use the reader/burner to read each one of your chips and verify them with the ROMIDENT software. One will be bad. You don't have an eraser, so fork out the $3 for a new blank EPROM (or PROM) as needed and use the programmer to program it. Don't even bother buying an eraser unless you build up a stack of bad ones worth as much as an eraser costs.
