I'm trying to use a 29F016 flash chip with my Turbografx, and haven't been able to get it to work. It's brought up a few questions at the same time that I was wondering if someone could shed some light on. Basically, I've added a 40pin ZIF socket to the back of my turbo that allows me to play games via EPROMs up to 8Mbit. I have a bunch of 29F016 roms kicking around from SNES repro's, and was wondering if it was possible to use them with the turbo rather than having to UV erase eproms? I use the same adapter boards as outlined here: http://www.mmmonkey.co.uk/programming-29f032-eeprom-on-gq-4x/
I tried to use these along with the programmer adapter in the turbo (so basically standard pinout ZIF in my turbo -> TSOP-Willem programmer adapter -> 29F016 on Adapter III board), however the game wouldn't boot, just a white or black screen. I tried tying A20 high and low to just use the first 8Mbit for my game, but neither worked. How should I go about using these on my Turbo?
Also, the HuCard pinouts I've been looking at state that pin 24 is /CE, but also A20:

So is it possible to use a 16Mbit flash chip with the turbo? If so, how would you wire it up?
Sorry, this is a bit loaded and probably really confusing the way I have described it. It's also ridiculous because I should just use a 27C080 EPROM, I know. I just happen to have a lot of free time and want to figure this out. Here is a picture of my turbo with the setup I'm attempting to use to play a game via the SNES Adapter board with a 29F016 on it.
