- 0.34b5: Known issues: Some flickering graphics.

- 0.34b4: Ernesto Corvi added Express Raider (Data East 1986) and clone (bootleg). The background tiles had a very ugly encoding. It was so ugly that our decode gfx routine will not be able to decode it without some little help. So thats why exprraid_gfx_expand() is there. Many thanks to Phil Stroffolino, who figured out the encoding. The bootleg version patched the rom to get rid of the extra opcode ( bootlegs used a regular 6502 ), the vectors hardcoded in place and also had the protection cracked.

- 10th November 1997: Thierry and Gerald dumped Western Express (bootleg set 1).

- 25th September 1997: Dumped Express Raider (US set 1).
