TBH, I don't use my New 3DS XL for GBA games for the exact advantages you listed by using a mGBA core emulator, plus the screen resolution/scaling just doesn't look right IMHO on the 3DS for GBA games. Here is a photo comparing the game start screen on my 3DS and on my RGB30: https://imgur.com/fA8EQP7 The 3DS screen doesn't look as bad as the photo shows, but it is nowhere as nice as on the RGB30's screen. I'm using the mGBA-rumble core on various handheld emulators and I'm not seeing any game play performance issues. I adore my 3DS, but I'm much happier just using it for DS/3DS games.

Awesome, thank you!!! Once my gba file was patched, I was able to play GG with rumble working on my Odin (1), Anbernic RG353M and my Powkiddy RGB30 (see ArkOS wiki on RGB30 for info on adding rumble). I also tried on my Miyoo Mini v2, but Drill Dozer wasn't rumbling on it; I likely need to do some updates on it first. I don't have a rumble pack for my Analogue Pocket, so I wasn't able to test on it.
Overall, I'd say this issue is solved with the simple workaround. Thanks!
The rumble (vibrate) option isn't working for the GBA retroarch cores on multiple emulator devices. I have set "Rumble: On" it in the options screen and the game restarts, but with message "A GB Player has not been detected. Rumble set to fallback mode. This requires a compatible emulator or flash cart." I have retroarch core options -> Input & Auxiliary Devices -> Game Boy Player Rumble option set (on mGBA-rumble core)
I'm able to play "Drill Dozer" on the same retro handhelds with the rumble working normally. Not sure why rumble is being disabled automatically on this game\?
