For what it's worth, I searched in Japanese, and it I could not find any accounts of people getting it to work with Windows 98. I found people asking about it and saying they were going to try it, but no success stories.
Granted, the vast majority of the info out there is about the PC-98 version anyway. Apparently, the PC-98 also not compatible with Windows 98, unlike Windows 95.
You've looked at this, right?

Haha ... it funny you should answer the question ... I've just been reading a bunch of your posts in the old "Anyone care to comment in-depth on the PC-FX hardware design?" thread (
http://www.pcenginefx.com/forums/index.php?topic=10536.0).
Thanks for searching out those pages, I certainly hadn't seen the 2nd one.
Perhaps I should be more specific ... I don't actually want to run the PC-FXGA within the Win98 GUI ... I suspect that that's never going to work.
Microsoft made a bunch of changes between Win95 and Win98 that screwed up it's ability to run old DOS drivers while within the GUI ... and since the PC-FX drivers are all DOS level, I don't hold out much hope (nor do I have much interest).
I've seen Fez's page before, but it's a pretty messy workaround to get the PC-FX to work in the Win95 GUI using SCSI drivers ... which I think was because the PC-98 was using a SCSI CDROM.
These days, the DOS machine that the PC-FXGA goes into is so slow that it's always going to be a secondary computer that can be dedicated to the PC-FXGA, while any real development work is done on a separate modern Win7 multi-core system.
The multitasking Windows GUI isn't really necessary, and the CD drive is going to be ATAPI, and not SCSI.
My goal right now is to try to get the PC-FXGA working in Win98's DOS 7.10 boot mode without using the Win98 GUI, and then update files over the network.
Since my earlier post, I've got the PC-FXGA playing CD games in DOS 7.10, so that's a good start.
Now it's back to Win95 to install the GMAKER and GMAKER PLUS files.
I was just hoping that someone had already documented doing something like this to save me some time.
