In the video the guy explains why he did it, and how he did it, and from the video you could probably do the same yourself, but would you want to?
Wulff Den explains that the reason he did it was on a whim and because when the movie came out in 2020, in the middle of the pandemic, the director explained that the movie must be seen on the big screen, so he compressed the movie down to fit on a small screen, the GBA 5 inch screen!
As explained the reason why it has to be on 5 cartridges is because each can hold 30 minutes at watchable quality and the movie in almost exactly 2 hours and 30 minutes.
The video runs lower than the GBA resolution at 192 x 128 and it has 6 FPS (Frames Per Second), but its claimed that it is just about watchable!
This isn't for everyone and watching the video is probably enough, and besides you would have to flash your own roms, not hard but hard enough, we wont be seeing this on sale anytime soon but its an interesting side project for anyone with time on their hands!
