retofinv.cpp: Added original Taito 68705 MCU dump, and moved bootleg 68705 MCU to its own new set. Renamed sets to make it more obvious which are bootlegs. Verified XTAL, dividers, and SN76489A type from pcb pictures. Added missing original Taito CLUT PROMs and fixed video/retofinv.cpp to be able to use those or the single bootleg CLUT prom.

Notes:
|
||||
- I derived the ROM names from the board diagram in the manual. There might
|
||||
be some mistakes. The diagram actually shows 4 PROMs on the ROM board
|
||||
(a37-17, -18, -19 and -20), while we only have one: 82s191n. I think it's
|
||||
possible that the single 2KB PROM replaced four 512B PROMs in a later
|
||||
revision of the board.
|
||||
- The rom names and locations are derived from PCB pictures.
|
||||
|
||||
- The video hardware (especially the sprite system) is quite obviously derived
|
||||
from a Namco design.

- Two bits of tilemap RAM might be used for tile flip, but the game never sets
|
||||
them so we can't verify without schematics.
|
||||
|
||||
- We don't have a dump of the original MCU. We have a dump from a bootleg MCU,
|
||||
which however cannot be the same as the original. The game works fine with it,
|
||||
but only when the flip screen dip switch is set to off. If it is set to on, it
|
||||
hangs when starting a game because the mcu doesn't answer a command.
|
||||
See MCU code at $206 and $435: when the dip switch is on, the lda #$00 should
|
||||
be replaced by lda #$01.
|
||||
- In addition to a dump of the original MCU, we have a dump from a bootleg MCU.

The game does work with it, but only when the flip screen dip switch is turned
