'High Rate DVD' HW (c) 1998 Nichibutsu
preliminary driver by Angelo Salese
TODO:
- rewrite v9938/v9958 video chip;
- fix h8 CPU core bugs, it trips various unhandled opcodes
- Implement DVD routing and YUV decoding;
- game timings seem busted, could be due of missing DVD hook-up
- csplayh1: inputs doesn't work at all, slower than the others too
- h8 type is almost likely to be wrong;
***************************************************************************/
DVD Notes:
- TMP68301 communicates with h8 via their respective internal serial comms
- First command is a "?P<CR>", which, according to the Pioneer V5000 protocol manual
is an Active Mode request. Manual is at:
http://www.pioneerelectronics.com/ephox/StaticFiles/Manuals/Business/Pio%20V5000-RS232%20-%20CPM.pdf
After returning a correct status code, tmp68301 sends "FSDVD04.MPG00001<CR>" to serial, probably tries
to playback the file ...
