Maybe it has some correlation with WEC Le Mans HW? (supposely that was originally done by Coreland too)

TODO:
|
||||
- sprite emulation (very likely that it can do zooming);
|
||||
- improve sprite emulation
|
||||
- road emulation;
|
||||
- tilemap scrolling /-color banking;
|
||||
- inputs doesn't work in-game?
|
||||
- dual screen output.

- Missing ROM data
|
||||
IC03 and IC04 are missing from the set.
|
||||
These look like "logical" ICs rather that physical ones.
|
||||
The main program code is dumped as 2x128k files p1a and p2a.
|
||||
The checksum routine does 4x64k checks, going by the routine.
|
||||
IC01 is the first half of p1a, IC02 is the first half of p2a,
|
||||
IC03 is the second half of p1a and IC04 is the second half of p2a.
|
||||
|
||||
IC01 FEFF bytes @ 0x00200 code at 0x000019FE CHKSUM A5 (00200 offset is just after where the checksum is recorded)
|
||||
IC02 FEFF bytes @ 0x00201 code at 0x00001A24 CHKSUM 87
|
||||
IC03 FFFF bytes @ 0x20000 code at 0x00001A46 CHKSUM 61
|
||||
IC04 FFFF bytes @ 0x20001 code at 0x00001A6A CHKSUM E0
|
||||
|
||||
Unfortunately the second half of p1a and p2a are empty, all 0xff.
|
||||
No other ROMs in the entire set match the checksums used in the POST.
|
||||
I am guessing they are bad dumps.
|
||||
|
||||
- Unmapped reads/writes
|
||||
CPU1 reads at 0x07fff8 and 0x07fffa are the slave reading validation values
|
||||
to compare to slave program ROM checksums.
