Sort of, i didn't catch all Italian keys but customized a bit your uk version to better adapt to my keyboard, and happy this way, thank you!

One thing: @Zuofu if you are here, are you OK with this being modified in this way and put on GitHub? Or if anyone knows them and are able to check, please do so. I'm happy to pull it from GitHub and just put the code in this thread if that is preferred, but it's getting a bit big for that really. I have given all credit in the README and left all the original comments intact.

I think this is fully working (for UK layouts) now.
(omissis)
I'd like to implement italian layout but i'm stuck into code since days... could you give some more info on keymapping[]? in which order is the array? it doesn't seem the scancode sequence of the real keyboard, but i probably missed something.
Thanks in advance!

Apologies, ive only just seen this. Are you still struggling? If so, let me know and I'll take a look. For future reference, raising an issue on github will get my attention quicker!

Repair Division / Sega Saturn possibly fried, st...
Last post by fix_metal_bis - October 27, 2025, 05:49:37 AM
Hello All,

Some nights ago I've been modding my Sega Saturn (Model 1 Jap White...) with the now famous FRAM mod. It's been really a while since the last time I've played with it, possibly ~ 2 years (after possibly a 5 years iatus).

Since I've been modding for a while I felt it would have been a snap, as I also modded several Mega CDs with even tinier FRAM chips. I did wrong this time.

In an attempt to rearrange cabling of the already installed switchless mod + mod chip, bringing all the soldiering on the upper side of the mobo, I've mistakenly soldered the +9V to the modchip VCC PAD, and also to the FM18W08 FRAM chip. Moreover, while doing the job, some former SRAM pads have lifted and gone, so I had to re-trace.

Long story short: the Saturn fired up, and the controller was unresponsive, it showed me the date setup screen, an freezed. After that, black screen.
Once I've figured out my mistake, I've removed the FRAM, and correctly soldered +5V to the corresponding pads, re-checked the former SRAM traces I've restored, and everything was fine. Firing up again, the Saturn is responsive, video and audio ok, but...
but now it just says "Checking on disc" no matter if the lid switch is close or open. This happenes even with the CD drive disconnected completly. The very odd thing now is sometime (likely, when all the caps discharge?) the CD ACCESS Led will blink, and sometime, when closing the CD lid opening switch, the CD drive will actually move the gears to move the laser unit. I didn't see the motor spin, nor the laser lighting up though.

So at least CPU and RAM are working, and even the basic BIOS is there. Though, I'm not entirely sure where to start scouting what it could have fried.

To be fair, I'm pretty depressed by damn mistake here, and I'm looking for similar experiences.

Thanks

I believe the CD-ROM drive on it is IDE (or standard PC SCSI?) All the games I play on it are from the IDE-CF card. I don't believe that CD-ROM is as must-have on PC98 as it is with FM Towns. :)

Yeah, CD-ROM drive is definitely not a must-have on the PC-98. However, as you know we all love to tinker with these old machines, so having CD-ROM capabilities is just another part of it!

Some PC-98 units use IDE for their internal CD-ROM drives, others like my Ap2 use what's called "file slot" and require an A-MATE SCSI card like the PC-9821A-E10 installed (not C-BUS).

Quote from: ateam on October 25, 2025, 12:37:52 AMThat said, devices like the ArdSCSino Plus are also great for machines like the PC-98! As long as you have the correct driver, it works just as a regular SCSI CD-ROM drive would.

Quote from: leonk on October 24, 2025, 06:48:37 AMThis is the problem I ran into with ZuluSCSI and CaptainYS' boot loader. While it works great for OS boot discs, games is hit/miss, with miss being more often the case. Many games require modifications to work (see his github repo) Downloading an ISO from the Internet and hoping it will work is frustrating.

Yes, this isn't really a solution, more like a fun curiosity. There are two people working on FM Towns ODEs right now, so we'll see how that plays out (and no, I'm not referring to Fixel, haha).

Quote from: ateam on October 15, 2025, 02:00:59 AMNote that I also bought a new-in-box external Panasonic SCSI CD-ROM drive for testing with CaptainYS' boot loader, and as expected, it works wonderfully (just so long as the software itself is supported by the booth method, which not all software is).

I gave up. Using CD-R's with the original drive gave me much better compatibility and overall success. We really need an ODE for the internal drive or some sort of PCB board that allows a ZuluSCSI/BlueSCSI to work as the internal drive correctly.

Last post by SomeGuy - October 21, 2025, 09:25:29 PM
Erm , are the CD Drive's bipolar caps particularly problematic or something? , I did replace one or two polarized ones and i checked the ESR of the originals and they measured the correct values so.

I also adjusted the laser power of the original pickup but it didn't help ,I have the spare laser installed at the moment , I upped the potentiometer far less on that one , just to be sure not to overdo it.
But that laser also just sorta spins the disc for a few seconds and stops like the original laser , I tried messing with the 6 adjustment pots but no dice , I guess ill try actually hooking up the oscilloscope and measuring the signals since nothing else has worked.
