Modern replacement for 32Mb V ROM?

[pollsoda]

First off, I'm new to repairing Neo Geo carts, ROM programming, etc so forgive my questions.

I'm trying to replace a V ROM (32Mb / 4MB in size) on an MVS cartridge and from some reading, it looks like you can't use a 27C322 because it's a 16-bit part.

I found another thread here ("27C322 as a 32mbit V Rom") that's several years old that suggests using 26L6420 with the SOP44 adapter or MX29L3211 with an adapter (one for programming, another for reading).

Is there a more straightforward way of doing this now?

Some googling led me to something like a "FUJITSU MBM29F033C-90PTN with TSOP Adapter III" that appears to be a 32Mb 40-pin TSOP 5V part on a 40-pin DIP. Will this work as a drop-in replacement?

I have a GQ-4X V4 (GQ-4x4) and the 16-bit adapter. What's the most straightforward way of getting a replacement V ROM - buying this part pre-programmed (from buyic) or ordering the part(s) and DIY'ing it? I'm comfortable soldering TSOP, etc if that matters.

Or is there a better part that will work in my situation?

Thanks for your help. I didn't want to necrobump the old thread, since some of the info may be dated now or changed since?

This is the thread the last touched on this if I'm not mistaken:

Concerning the "FUJITSU MBM29F033C-90PTN with TSOP Adapter III", the only surefire approach would be to get a datasheet for the 40 pin adapter used and compare its pinout with that of a regular 32Mbit EPROM (or more specifically, SNK's V ROM pinout).

If you come across the 36 pin version on buyicnow, keep in mind that adapter is meant for SNES cartridges, which use a custom pinout.
