I was wondering if anybody recognised the company that made this ROM from the logo (The 2 wavy lines):


It looks damn familiar to me but I can't remember the manufacturer name and I don't want to scrape off the label any further just yet. Ultimately I am trying to dump it for preservation and also want to leave the physical ROM as unsullied as possible, but I need the correct manufacturer for it to work with my TL866 Pro.

Any ideas folks?

Ahh, of course, thank you!

Still didn't work until I told it not to check the chip ID.
