Sintax GBA time again! There are so many of these. Dumps will probably come a bit slower from now on, since most of everything I have left has the second-version protection with trap addresses, which takes a bunch of trial and error to work around.
The Lord of the Rings IV - The Fellowship of the Ring
Cartridge ID: E12-U15
Today's "new" game comes with a loose Lord of the Rings theme. And this game has the music bug, despite being a fairly late-on ID. There really isn't that much rhyme or reason to which ones have the bug and which don't.
Overwritten header bytes are 90 AE 4B 4A 59 4A - but after some investigation I've found it doesn't really have any protection-related significance, since I have another game with the same bytes here but completely different trap addresses and mirroring. I've also found another location where this data is stored, scrambled, so maybe I'll stop noting them here for now.
Rayman IV / Rayman - Sunshine of Trip
This one was dumped by RibShark who kindly allowed me to repost it here!
I previously dumped the Russian version, and here's the English. The only in-game difference seems to be the title screen.
Interestingly, unlike the Russian version, this one did have trap addresses, making it trickier to dump. This difference seems like it may be accounted for by different PCB revisions rather than per-game - so different printings of the same game may exist with different "levels" of protection.
