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 :-)
Here are some screenshots
