Seletron / Olympia Long Beach
|
||||
Olympia probably took care of distribution, PCB and game by Seletron
|
||||
|
||||
PCB was broken, and there are no known references.
|
||||
16MHz XTAL, M6800 @ 500kHz
|
||||
2x 5101 sram 256x4bit (256 byte) battery backed
|
||||
4x 4045 sram 1kx4 (2K byte)
|
||||
Hardware notes:
|
||||
- 16MHz XTAL, MC6800P @ 500kHz
|
||||
- 2x 5101 sram 256x4bit (256 byte) battery backed
|
||||
- 4x 4045 sram 1kx4 (2K byte)
|
||||
|
||||
6800 hits many illegal opcodes (0x02), though it's harmless.
|
||||
Maybe they meant to inserts nops (0x01) to remove debug stuff
|
||||
or to make room for future additions?

Speed Race is on the same hardware, no mention of Olympia, but it is
|
||||
listed online on Olympia game lists. It is a reimagination of Taito's
|
||||
Speed Race, not a bootleg.

|
||||
|
||||
Speed Race PCB where this dump came from had an incorrect CPU in place (MC68B09)
|
||||
maybe from a wrong repair. PCB label: Seletron, 10-50058. Less ROM data than lbeach.
|
||||
|
||||
TODO:
|
||||
- discrete sound
|
||||
- unknown writes (most of it is sound)
|
||||
- improve colors, lbeach is monochrome but what about speedrs?
|
||||
- right side of screen should be cropped? but speedrs sprite collision check
|
||||
wouldn't work then
|
||||
- some unknown romlabels (see "x")
|
||||
- lbeach 93448.h4 rom is a bad dump? it misses animation frames compared to
|
||||
speedrs, but when compared to enemy cars, it looks ok
