Help Emulating a Famiclone dump (gamezone 118 in 1)
« on: January 16, 2018, 04:12:23 PM »
I'm hoping this may be more obvious to people who've done more NES stuff, but I'm having trouble emulating the dump I've made of a gamezone 118 in 1 plug and play famiclone.

It's an older plug and play in the scheme of things (probably bought it a good few years ago second hand, the latest date on the PCB is 2003) - so it's not OneBus based as I was hoping. Inside it has two ROM chips, a 16MBit one that I think is for PRG and and the other 8Mbit one is for CHR. I've dumped both of them but I can't find an obvious fit in terms of existing mappers, but I don't want to spend ages reverse engineering if it turns out there's a working mapper already for this type of hardware. The PCB with the NOAC and ROMs on is marked "BELLESON" which could be Macro Winners (who I think use "BS" sometimes?)

Both ROM images are here, hopefully this isn't a bad dump:

Basically Mapper 126 (Super Joy), although Nintendulator's and Nestopia Plus' CHR bankswitching is still off.
Is it within the realm of possibility that you mistakenly flipped the 256 KiB banks during dumping? Because it works perfectly as Mapper 126, CHR and all, all 118 games, if I invert CHR A18 in Nintendulator. It may be a PCB variation, but it seems kind of odd, because CHR A19 is normal.

Interesting, this was done by desoldering the flash chips and reading them with a universal programmer, inverted banks seem very unlikely (shorts between signals are the only fault I tend to see). Probably more likely a PCB variation. Thanks for finding this out so quickly! :)

Just to be sure I am not getting things wrong: is "Fire Fighter" (game #118) really just a wacky name for a Super Contra variation?

For anyone just wanting to play this, this is a fixed ROM for Nintendulator with the banks swapped (I know this is a bad idea, but it works for now and it's named clearly).

.nes]http://davidstech.net/games/multis/gamezone%20Plug%20and%20Play%20118%20in%201%20(Mapper%20126,%20inverted%20CHR%20A18)%20[f1].nes

I will remove this once an emulator with the proper mapper is available.

I don't know if it's going to work when I put back together now either, I fear I damaged the PCB during desoldering.

Oh well. I have implemented it as submapper 1, to be supported in the next Nintendulator-NRS release, whenever that happens.

Unfortunately these pages no longer exist but I will have to put a link to download that multigame
