post the MD5 of the gameboy player image you are using...

Sure, here it is, assuming you want the checksum:

d8b804120e78602fb8ccac6852b37288

Your MD5 doesn't match any of the five found on redump.org so it's either corrupted, scrubbed or it's not listed on redump.

Dolphin reads it like a treat, so I presumed the ISO itself isn't an issue.

Well then I don't know. The contents of the disc should be pretty small. How big is the ISO ? You may want to try a 1:1 rip with Swiss.

The ISO was resised for a MiniDVD, so 1.4GB.

Did you resize it or did you download it that way ?

Downloaded that way. I tried an NTSC ISO that wasn't resized, no luck with that either.

1:1 dumps do not need any resizing since they are... 1:1. They are fixed at 1.4GB. Try to find a real 1:1 ISO.

Alright, so having no luck with a 1:1 ROM with a recognised checksum, and no luck with SSBM being burnt to a disk, I'm finally gonna come to the conclusion that they're bad disks. Gonna either: buy some more expensive disks or: splash out on a legit GBPlayer disk.

I don't remember if it's been asked but did you tweak the laser pot ?

Yeah, I did all that soon after I bought the GC.
