NES-TKROM cart list
by koitsu on 2009-12-19 (#54189)
I was hoping to find a list of NTSC TKROM + battery-backed WRAM carts, since the pinout should (not 100% sure; TEROM is, so I assume TKROM is) be compatible with EPROMs, but wasn't able to. The list I've put together so far is:

AD&D - Pool of Radiance
Base Wars
Baseball Stars II
Crystalis
Deja Vu
Gold Medal Challenge '92
Kirby's Adventure
Magician
Might & Magic
Shadowgate
Tecmo Super Bowl
Uninvited
Wizardry - The Knight of Diamonds
Wario's Woods

Anyone have any additions?

Should I stick/track this stuff in the Wiki under TKROM?

The pinout isn't compatible with EPROMs, it needs rewiring like any other commercialized board with ROMs larger than 32KB.

TEROM appears to be a development board, so it accepts EPROMs in order to make the life of developers easier, but as far as I know no board compatible with EPROMs were sold to the public (besides NROM an CNROM).

Welllllllllll crap. That blows my fun. :(

Well, you were willing to desolder the original ROMs, and IMO that's the hardest step in making a dev cart. Rewiring is the easy part. Give it a shot.

Soldering isn't the hardest part (for me). It's the fact that I can't find a coherent wiring diagram for EPROM, EEPROM, or Flash --> TKROM. :-) If I had something like that I'd likely be in better shape.

Actually, I just realised I'm not even sure why I'm bothering with this step quite yet... should just get a PowerPak until I'm ready to harass bunnyboy into etching and selling MMC3 blank carts on RetroZone, haha. :D

Wrong, all Nintendo boards with one of the slot equal or below 64kb has compatible pinouts, and all non-Nintendo boards have compatible pinouts as well.
This include NROM, CNROM, SEROM, TEROM, SAROM, SBROM, TBROM, MHROM and also the PRG or CHR of other boards (CHR of SFROM, PRG of SCROM, etc....)
I haven't completely vertified that (since I don't own all boards) but that would completely made sense. Unless Nintendo wanted not to use the same pinout for the same EPROM of the same size (which they did in funky board like SL1ROM and MMC5 games I think).

About the rewriring shemes in fact they're the same for all boards (for a given PRG or CHR ROM size), so the instuction for SLROM will work just fine on TKROM for example.

Sorry, I though the limit was 32KB, not 64KB. I guess it's because I haven't seen many games that had 64KB of CHR and/or PRG. Anyway, TKROM for sure isn't directly compatible with EPROMs.

You could add Tecmo NBA Basketball to the NTSC TKROM list as well.

You can do such searches on the NES DB site: [url=http://bootgod.dyndns.org:7777/search.php?keywords=&region=USA&region_op==%60@%60&system=NTSC&system_op==%60@%60&pcb=NES-TKROM&pcb_op=LIKE%20%60%@%%60&field=2&order=asc]example search[/url]

how do you change the mirroring on an tkrom?

I have NBA basketball and i want to change the mirroring to horizontal but i can't find any of them pads....

by tepples on 2010-01-26 (#55718)
As far as I know, the only MMC3 boards with mirroring solder pads are TEROM and TFROM, which are designed for back-compatibility with games designed for D*ROM. The rest have either four-screen mirroring (TVROM), MMC3 CHR-bank-controlled mirroring (T*SROM), or standard MMC3 mirroring (every other T*ROM).
