Summary 07731: All sets in zr107.cpp: Mask rom tests as bad
Description When doing a mask rom test in test mode, six (midnrun and windheat) or four (jetwave) will mark as bad. These roms being:

midnrun/windheat: a-11 to a-16; a-11 and a-12 being the two k056832 tilemap roms and a-13 to a-16 are the texture data roms.

jetwave: 4d, 9d, 13d and 18d; texture data roms
Steps To Reproduce Press F2 to enter service mode, select "MASK ROM CHECK" and wait.
Additional Information All sets in gticlub.cpp except for hangplt (freezes during its mask rom check different reasons) have their mask rom check pass. jetwave uses the same video board as gticlub would use yet jetwave fails its mask rom check while gticlub passes its mask rom check.

Possible bad rom dumps or something else?

I can get jetwave to pass the mask ROM test by changing the ROM loading to match the one used for gticlub but then textures get worse (see attached screenshot - left current, center passing mask ROM test).

EDIT: Actually nevermind, found the solution. So jetwave and clones are fixed, the other z107 games still fail.

The solution was under my nose this entire time :S...mostly. I wonder how zr107's rom loading was incorrect all this time (but remained correct in gticlub)? I also ask what the right most screenshot was?

Maybe the 056832 tilemap roms should be loaded as "ROM_LOAD32_WORD" after noticing how the tilemap roms were loaded in asterix.cpp and moo.cpp.

56832 is difficult to deal with, it has per driver / hardware configs.

The right screenshot is the difference between the left and central one. The uploaded file is what pngcmp outputs.

No kidding. I attempted my said suggestion of loading those tilemap roms as "ROM_LOAD32_WORD" and made the tilemap graphics worse. The rom test still showed the tilemap roms as bad showing the same address.

Something about Konami arcade hardware makes me feel uneasy.
