"Now (That’s What I Call MAMEing) 33"
Peter and Morten dumped the internal ROM from Knights of Valour 3, the China
/ Taiwan / Hong Kong only installment in the series, and first game to make
some significant changes to the gameplay formula.
Metallic bypassed an additional check the game makes for an FPGA on the ROM
board, and I fixed up a few holes in our video emulation needed to make the
game look correct (it runs at a higher resolution of 512×240 pixels) There
are still some slightly odd looking visuals in some stages where the bottom
row of background tiles is repeated, but I think that’s because those
backgrounds were originally designed to run at 224 resolution and IGS were
simply hoping nobody would notice.
Here is a video, I don’t play well here because I put the game on the
hardest difficult in Service Mode. Video shows the save cards work fine in
the MAME emulation anyway :-)

: 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.
