- Truco-Tron - (c) 198? Playtronic SRL, Argentina.

- Written by Ernesto Corvi
- Additional work by Roberto Fresca.
-
-
- Notes:
-
- - The board uses a battery backed ram for protection, mapped at $7c00-$7fff.
- - If the battery backup data is corrupt, it comes up with some sort of code entry screen.
- As far as I can tell, you can't do anything with it.
- - Replacing the battery backed ram with an eeprom is not really an option since the game stores the
- current credits count in the battery backed ram.
- - System clock is 12 Mhz. The CPU clock is unknown.
- - The Alternate GFX mode is funky. Not only it has different bitmaps, but also the strings with the
- game options are truncated. Title is also truncated.
- - At least one bootleg board exist.
