I've purchased my first video slot  (Gamemaker 7000) about 4 weeks ago and I'll soon be experimenting with burning new games.

My EPROM eraser and my "True Willem GQ USB Programmer" have already arrived.  I've ordered various quantities of  512KB, 1.0 MB, 2 MB & 4 MB EPROMs from various EBay sellers, and they'll be arriving at different times.

If the larger chips should happen to arrive first, can I burn a 512 KB game onto a 1 MB or 2 MB chip, or will I encounter problems?  I wouldn't think so, but I'd rather get some feedback first.    I know it makes better financial sense to wait until the smaller chips arrive, but I'm excited to try it.

Can you help?     ......Howard    (the RV Doctor)

The short answer is yes but not ideal as you pointed out.   This was done by a few members on the old board for S+ machines with replacing the c64a chip.   I am not sure if the bally will accept it or not but in theory yes since the socket takes a 512 and a 1mb chip.

I have had no problems using over sized eproms on my GameMaker 7200.

Hi Dave: I  appreciate the feedback.  If it worked OK on your Gamemaker 7200, do you think it would work OK on my Gamemaker 7000?   I dunno.

The S+ required burning the data at an offset. Is that the case here, or can you burn the data onto the larger chip at position 0x0000?

To corroborate past answers, yes you can burn a 512K on a 1 meg eprom, but be sure to save the 512K file because when you read and copy the bin from the 1 meg eprom it will say is is 128K, which is a 1 meg file. I believe the burner probably zeros out the unused space.

You can extract the 512k segment from the 1M chip when reading it by restricting the read segment, but keeping the original file is much simpler. yes propeller

What about the offset (when burning the 512k file to the 1M chip) . Is one needed? Scratch Head

No offset, I just load the file up and burn the eprom as if a 512K chip was in the burner.
