Bad ROM? New Battery? I'm lost...
So I bought a used copy of Mario's Picross at a convention. Back in the hotel my friend brought his Retron 5 for testing games and stuff. Put it in and the game works fine. The retron makes it own save file so you never know if the orginal is intact or not. (don't truely know alot about the retron) So when I get home I put it in my GBA SP and it boots up and says continue your saved game press A to start. As soon as you press A it goes to a white screen and never goes past that. So I figured the battery is dead and change it. It does the exact same thing. Then I tried it with no battery at all. Still the same. I try the game in every version of gameboy I own including a super gameboy all the same. The werid thing is I gave it to my friend and he says it works perfectly fine in his Retron still. So whats up? Is the ROM just corrupt or is there something I can do here. I really dont want to trash a game that possibly could be fixed. Also unsure what the Retron is doing to make the game work but when its in original hardware is crashes after loaded the "save file".

It's long and in two parts but this Game & Watch Gallery 2 was ultimately the same fix (reflow pins):
It was also working on some systems and not others (IIRC, tested between GBA SP and Super Game Boy) with a freeze/blank screen when loading.
Good luck!
I was screaming in the comments section "reflow first!" while he removed and dumped chips and we ended up waiting for a Part 2. Removing the chips to dump and resolder was effectively reflowing them, so he did eventually come to the same easy fix!
...and MrPete1985 can get his thanks right here in this thread.
I guess this happens to GB games more than you'd think because they get more stress (being portable).
