I'm having a similar repeated crash on two separate retroarch cores on my Miyoo Mini. In fact at the moment the Miyoo Mini is auto loading to the same crash and I can't using the device. I'm guess I need to remove the rom completely for the SD card and try to reboot. Considering the Analogue Pocket isn't emulation it shows there may be coding issues - and it not being the devices or software.
The cores were mgba and gpsp - this is the first game I've seen crash both of those cores.
The game works fine on my OG GBA and Gameboy micro using an EZ Flash Omega though.
UPDATE: Nothing wrong with the game - just a corrupted file that must have happened when transferring to my SD card. I just re-downloaded it and it's fine now.

It's been played thru completely many times on both cores and on the AP, I've only seen it do a kind of hard-crash (a freeze with an ugly noise?) with an old/less reliable SD card or if it got corrupted while copying over. If you hold A+B+Down+Left while booting do you get the correct checksum? (A4A932B1)
If there is anything we can do to increase reliability on emulators we will do so! (in fact, we had to make many special considerations for it to run on gpSP!) - if you could grab a short video of it crashing on the miyoo it may help us narrow it down, we'd be very grateful!

Hi, just some feedback. It seems my download had picked up some corruption. It's working on my Miyoo Mini now - and with rumble too!
I'm also lucky enough to own an EZ Flash Definitive Edition and rumble working wonderfully on there with my Gameboy Micro as well. I think the Micro with rumble is going to be the way I go for my first play-though. I love that device and playing such a well made new GBA game on it in 2023 is beyond a treat!
