Is a USB TL866II sufficient to burn 90's era WPC eproms?
Does it require a specific OS?
What EPROM should I be using for my 90's era WPC games and whats the best/economical source for them?
I think a lot of them use 27c040 for the game rom but there's a section in the manual that will tell you exactly what rom chips are used in each location. I have always bought used lots off of ebay. You will want a uv eraser to clean off any old data or incase you make a mistake and write the wrong rom file.

Use the proper ROM chip size for the size of the ROM. Some WpC games used 1Mb, 2Mb, 4Mb, and later WPC-95's used 8Mb.
The size of the image file is almost always the indicator of what chip to burn it on.

In a lot of cases a larger eprom can replace smaller eprom of the same pin count if you put the data in the right place or even simply repeat the image file until the chip is full.

I can just binary merge/copy the same rom until it’s the correct size right?

In most cases yes. I use windows notepad to make batch files that run command prompt strings but there is many ways to do it.
Say you have a 27128 image file you want to burn on a 27512. The 27512(512K) is four times larger than a 27128. In notepad you would put this line in. Save it as a .bat file in the directory of your roms and then run it.
copy /b file.128+file.128+file.128+file.128 file.512
2732 can almost always replace 2716
W27c512 can almost always replace 2764 - 27256
27c040 can almost always replace 27c010 and 27c020
and etc. Then you don't have to keep so many different flavors of eproms on hand. Back in the day a 27512 might have been more expensive then four 27128 but now you can find most EPROM salvage pulls for a buck each or less. 8mbit might be the exception, those are more pricey. I buy the ones out of china that are cleaned, legs straightened and pre erased. I hate scraping off 30 year old label gunk.
These would work for AFM 1.3b?

Image file 1028kb which is 8mbit so yes m27c801 will work on WPC MPUs assuming the chips are as advertised in working condition.
When you get into 1M+ the naming gets a little funky. 27C040 27C400 27C4001 are all basically the same thing.
I have a good # of EPROMs available from the smallest starting at 2716, 2532, 2732 etc all the way up into the larger 1mb, 2mb, 4mb & 8mb.

I finally ran into a few chips that weren't listed in their library. Sometimes you can find the same pinout of another chip (usually from the same manufacture). Just make sure VCC, VDD, and VPP are correct, and you can still use (you can find this on the data sheets). the TL866II is good for majority, and has most chips listed in it's library. I've never had an issue with WPC games.
Think the highest programming voltage is 21 or 25 volts, had one chip I bought that was higher... so it can't be used with this programmer .
