Morten and Peter managed to dump the internal rom of Dodonpachi Daioujou
Tamashii, a Chinese release of Dodonpachi Daioujou on PGM2 hardware that
offers an ‘easy’ mode.
extracting this one was more difficult (I’ll update this post / do a new
post explaining why later)
unfortunately for now it also appears to expose some more bugs in the MAME
ARM core, these are being looked into, but basically a lot of the sprites end
up with a value of ‘0’ for palette selection instead of the correct value
causing them to be rendered with incorrect colours. There are no additional
video attributes being set so it seems logical to conclude it’s a CPU
emulation problem at this stage.

Yes, the service mode really renders at the wrong orientation, bit lazy
considering they didn’t have a bios to worry about and all the code is on
the game boards.
*edit* MetalliC traced down the ARM CPU core bug and fixed it, resulting in
correct colours. This also potentially improves things in the GBA driver.
This fix might not make 0.193 as it missed the deadline, so unless those in
charge of the release decided that it’s important the 0.193 version will
have broken colours shown above instead. *edit* Looks like the progress to
fix the colours will be in 0.193, unless it gets backed out again at the last
minute.

.. and a video of it running in MAME

: "The King of Fighters ’98: Ultimate Match HERO (PGM2)"
: Here are the first Work in Progress shots from The King of Fighters ’98:
: Ultimate Match HERO after Morten Shearman Kirkegaard and Peter Wilhelmsen
: dumped the internal rom.
: They show that the PGM2 emulation still needs work, especially with a missing
: sprite enable register and screen resolution control. There is also no music
: at the moment, and a hardlock in attract mode.
