Do you need to change the program rom for this to work?
I had seen an old sales thread on KLOV about replacing the KI2 hard drive with an IDE DOM, as well as post by @acblunden2 considering a DIY version, and thought, 'Well, I already have half the parts, let's give it a try.' I particularly like having the DOM on this board since it's shorter than one of the heatsyncs, and doesn't stick off the edge of the board like the CF adapter I have. I've only played a bit but didn't notice any unusual behavior vs my hard drive (though I'm admittedly not that discerning when it comes to this particular game).
In case you want to reproduce this, I used a USB-IDE adapter, some gender changing pins, a 44 pin DOM I picked up off eBay, and good old diskpart and chdman.exe. I assume you already have a CDH and the boot rom done. The process is identical to creating a CF card, but here you go:
1. connect DOM to windows10 laptop via the USB-IDE adapter and gender changing pins
2. run cmd.exe with administrator permissions
3. at command prompt, type "diskpart" enter
4. type "list disk"
5. look at the list for the DOM, mine was "DISK 1"
6. type "select disk 1" with the '1' being wherever your DOM is
7. type "clean"
8. type "exit"
9. cd over to wherever your chd is (instructions here to make a chd, or just find one online...)
10. type "chdman extracthd -i kinst2.chd -o \\.\PHYSICALDRIVE1 -f" (again with the 1 being the drive number from diskpart)
That's it, plug it in the board.
Promptly lose to the computer, hit test mode and adjust the difficulty. Lose again. How do you combo again?
Plug in SF2CE...
edit: yes I can make you one. PM me to coordinate.
I really like that this doesn't stick out like a CF card solution
