I'll test it to see if I find something incorrect which I don't think so. :-)

Thanks.
I have not tested the joy stick.

!!! WARNING !!!

Latest emsx_top.pld (20080525 for OCM board) have all "...FF FF FF FF..." chars at the end of file. oO
I think that this PLD is not a valid file to use with PLDLOAD.COM why normally it have all "...00 00 00 00...".

Therefore, you do not load it if you do not have a ByteBlaster2 in order to recover OCM!!!

HRA!, do you confirm it?

Now, it checked again. (PLDLOAD EMSX_TOP.PLD)
It started.

caro's "Compression BIOS (MSX2+ compatible)" is adopted.
Therefore, the dumping result of EMSX_TOP.PLD differs from before.

Although starting is somewhat slow, it will start, if it is waiting patiently.
If you want to make starting quick, BIOS will be put into SD card.Big smile


Therefore, you do not load it if you do not have a ByteBlaster2 in order to recover OCM!!!

ByteBlaster2 can be made easily.

The cause of the voice noise of DE1 was found.
I checked that corrected and a noise was lost LOL!

It releases, after testing to a slight degree Tongue

According to sources PLDLOAD, it does not control the content PLD-file.

Wow, cool! Thanks for supporting DE1, Mr. HRA! I love that board so much. Do you have instructions on how to build cartridge slots for DE1? I assume I just have to connect 50-pin connectors to pin headers on DE1.
