    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

    you may find cartridge dump in MAME crack its protection, or decrypt some data or smth else like that basically same type of task as crack some PC game to play it for free :D nobody. at various points it was Elsemi, Deunan Knute, or me

    Weird StarHorse EX Naomi motherboards.

    it's just one of later revisions Naomi 1, you may check some notes there https://github.com/mamedev/mame/blob/140b1ca07adda3edc8b4d0830211f586b97e07cc/src/mame/drivers/naomi.cpp#L86 they was mainly used in games which uses RS232 peripheral devices, like Star Horse or Mushiking series, and number...

    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 this list is way too outdated (~10years I think) and not recommended to use, it also have wrong information in number of places.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...

    NAOMI 2/Chihiro/Triforce Card Reader Emulator (Initial D3/WMMT/Mario Kart/F-ZERO AX)

    yep, this one looks pretty good to me, good work :)

    NAOMI 2/Chihiro/Triforce Card Reader Emulator (Initial D3/WMMT/Mario Kart/F-ZERO AX)

    not sure about baudrate, but 8E1 part are correct, I've checked "RS422/RS232C BD DOC" MCU code and it initializes serial port in this mode.

    NAOMI 2/Chihiro/Triforce Card Reader Emulator (Initial D3/WMMT/Mario Kart/F-ZERO AX)

    yep, you did it right. but it seems something went wrong, perhaps not correct serial comms settings like parity or stop bits count ? I'd imagine these things might be configured by CRW DIP switches, so even if InitialD games uses exact same device, in theory they may use not the same UART...

    NAOMI 2/Chihiro/Triforce Card Reader Emulator (Initial D3/WMMT/Mario Kart/F-ZERO AX)

    you can't Naomi 1 != Naomi 2 in CN8 part, N1 have there custom RS422 serial comms (connected to MIE MCU), while in case of N2 InitialD you have at CN8 standard UART (connected to SH4's SCIF serial port). that's why Derby Owners Club games uses setup like: Naomi 1 CN8 <-RS422-> 838-13661...

    NAOMI 2/Chihiro/Triforce Card Reader Emulator (Initial D3/WMMT/Mario Kart/F-ZERO AX)

    I'd recommend to forget about that. N1 CN8 are Sega's custom RS422-like serial interface, no one knows how the heck it works at hardware level, at software level uses custom protocol to communicate with RS422/RS232 interface board. RE'ing of these sounds way above your (current) skills, if you...

    NAOMI 2/Chihiro/Triforce Card Reader Emulator (Initial D3/WMMT/Mario Kart/F-ZERO AX)

    @AbolishedEnigma you've did something wrong, captured data looks garbage nonsense. check beginning of this thread for InitialD reader logs, DOC should be almost the same.

    Came across a 3S Asia *CD* version?

    it's hard to say, so far we have none dumps of any SFIII 3rd ASIA carts BIOSes, neither CD nor NoCD versions. btw, @Darksoft
