Summary	01061: rodland: Report from a PCB owner about ROM names.
Description	I went to repair a Rod-Land PCB this weekend. Grabbed the roms, burned the replacements for a couple of suspected failed chips, and .... Total garbage on screen instead of sprites and backgrounds. Backgrounds made from a mess of sprites and vice versa. Switching roms rl_23.rom and rl_14.rom fixes this - someone has them the wrong way around in the romset, and thus in the driver too ;-) I don't think we can really argue with the PCB on this matter. All seemed well, until I tested the "hidden" Rod-Land levels (coin, 3x up or 3x down depending on region, start). Backgrounds a jumbled mess of tiles. I tested it again in mame, looked fine there. PCB did not agree. I took a look at the driver source, and noticed where a rom image is read in non-sequentially, in blocks of a mishmash order. WHile it might work to have a jumbled up rom read for a jumbled rom, it's definitely not valid on the PCB. After a few minutes with a hex editor I've rearranged the romfile to match the layout of the hack, burned it, and that works fine. So - to recap, rl_23.rom is jumbled up and wrong, and 23/14 are switched, both problems exist in rodland.zip. Maybe someone wants to fix it, mail me at james@bloodflowers.org if you want the repaired 23 image. Oh, aside from that - the Japanese PCB I've got actually appears to use world region rl_23.rom and rl_14.rom - I tried the jap region images first and the board didn't like them at all. The only japanese romset ones my board runs with are 1, 2, 3 and 4 - rest same as world version.
