    Naomi multi BIOS (fixed with proper bootstrap)

    target hardware thing I'd guess. arcade ver was developed for specific cabs with specific displays, 31kHz, while home ver was made for common 1998 TV sets, 15kHz

    Decathlete for STV finally working!

    not a single fuck was given to missiles explosions at some distance during development of this hack ;)

    Naomi multi BIOS (fixed with proper bootstrap)

    I think this game designed for VGA only

    Naomi multi BIOS (fixed with proper bootstrap)

    probably it's it, there was no other (working) hacks of this game to my knowledge. no idea about 15kHz, is there any problems with that ? sorry no links. I'm usually do some hacky stuff, share it and then delete (because it's useless for me), but I think here should be links in some thread where...

    Naomi multi BIOS (fixed with proper bootstrap)

    you mean my netboot hack of HotD2 ? it does include older revision of BIOS, which runs 1st and then game itself. so, in theory, it doesnt care at all which BIOS ROM chip is in NAOMI.

    Decathlete for STV finally working!

    well, there is 2 revisions of this game currently dumped. there is some chances newer revision "Decathlete (JUET 960709 V1.001)", which was used as base for this hack, had something broken while Sega was trying to fix something else in older original revision.

    Capcom Vs. SNK 2 password

    it was awhile ago and I barely remember the context, IIRC they are opposite to 2 previously known passwords, i.e. disable back some features. not sure if it's totally correct, but if anyone really interested to know he may try to enter one and then another passwords and check result

    Dimm vs NetDimm

    no need to over-complicate things, desolder and flash directly to 4.02 works just fine, this was confirmed many times

    Naomi Widescreen Hack

    have you checked links to dreamcast-talks etc forums ? sure, system load (and possible performance too) will be not exact same as original.

    Naomi Widescreen Hack

    as was said above - FOV change. i.e. games still works in 640x480 but ratio changed to fit nice on 16:9 LCD screens it is a bit more complex in case of 3-screen F355 but same principle - they changed view matrix values to make in look good on flat line of 3 screens

    Different Behavior with 4.01 and 4.02 DIMM Firmware

    there shouldn't be any difference between 4.01 and 4.02 in case of netboot, .02 hack affects CF boot only. it more smells something hardware-wise, bad RAM or smth like that.

    Sega Naomi NetBoot Games List Working/Not Working/Untested/Missing

    it doesn't say that, list at page 4 is about netboot "conversions". the game itself dumped, it's just nobody cared to crack it to boot from DIMM. this list is way too outdated (~10years I think) and not recommended to use, it also have wrong information in number of places.

    Sega Naomi NetBoot Games List Working/Not Working/Untested/Missing

    only 2 Naomi is not enough, you'll need at least 4 regular Naomi 1/2, plus one more 2x-PCB multi-board main unit, all of them should have comm.boards and should be connected via optical network. each of 4 regular Naomis also should have card reader. only in this case game will work. so, very...
