0.34b3 [Zsolt Vasvari]


- Clone Silver Land shouldn't be a clone of River Patrol, it's a totally different game (skiing instead of boat rescue), made by someone else! It's just a cleverly-disguised bootleg. I think it was Zsolt who stated this when the games were first added. It used to be mentioned in one of the text files that came with MAME, but I think it got wiped out once gamelist.txt became automatically generated. The Dog


- 0.140u3: MASH fixed sprite colors in River Patrol. Swapped gfx2 roms ($0, 800).

- 0.122u8: Changed River Patrol (Orca) to parent set. Renamed (rpatrolo) to (rpatrol).

- 0.104u9: David Haywood added clone River Patrol (Orca). This set came from a 'Silver Land' board with Silver Land GFX roms, however the program roms are nearly the same as River Patrol but appear to have an original ORCA copyright.

- 6th November 2005: f205v dumped River Patrol (Orca).

- 0.53: Swapped gfx2 roms ($0, 800).

- 0.34b3: Zsolt Vasvari added River Patrol (bootleg 1981) (rpatrolb) and clone Silver Land. Don't be fooled by the completely different graphics in Silver Land, this is the same game in disguise.

- 2nd September 1998: J-ROM dumped River Patrol (bootleg).

- 24th June 1998: Dumped Silver Land.
