the photo i've seen shows an eteprom board with no obvious alterations, so i'm assuming that's what's going on. away from home right now but i've got some famicom donors stashed away to try this on a cart.

If on ETROM, the city must be smaller than the standard 120x100 cell city.

It turns out it's 76x76.

A few other changes have been made to compensate: PD/FD/RCI zones are 2x2 (not 3x3); power plants, stadia, and seaports are 3x3 (not 4x4); airports are 4x4 (not 6x6)

We'll know SimCity is getting bootlegged if eBay prices for same-board Koei games (Bandit Kings of Ancient China, L'Empereur, Nobunaga's Ambition II, and Uncharted Waters) shoot up.

Probably not a huge risk there, as the NES version of the PCBs are all on games that are prohibitively expensive already.

Argh, MMC5! Won't work on a flash cart.

Might. It's not using much of the MMC5 beyond 8x8 attributes w/ 16k tile mode.

I wouldn't be surprised if Loopy's MMC5 implementation is adequate.

It has screwed up graphics on Everdrive. It says it's loading on Powerpak, I have the loopy mappers, but then is just a black screen. So it does not appear to work on flash carts currently

Yeah, this is probably the only game that stresses the MMC5?

@lupin3rd

To make it from famicom boards would be easier since there must be a pile of Koei games in every bookoff shop :lol: (saw one 2 days ago, complete box for a few hundred yen).

But then MMC5 boards are longer than other Famicom cart boards. How would one roll a JOINT to fit it and the board in the NES Game Pak shell?

there are low profile adapters available that will fit a tall famicom board in a nes shell. may require relocating some components but it can be done.

Why am I giving ideas for making repro :lol:

Jedi move: there is no such thing as pile of Koei famicom games, no such thing.

The problem there is that NES owners would need both the gigantic ETROM PCB, as well as a 72-pin adapter, all jammed into an already crammed cart.
