I have started to document my test procedures in test.md in the root folder.
So, this test is to inject each frame of .a18 audio (every 40 bytes of payload) into the first frame of the working mvp.bin Region 1, Frame 1.
The audio payload is 8560 bytes long.
There are 214 frames to test. Currently, I am hoping to isolate just the first 1-5 that crash the projector or cause errors projecting (light flicker, carousel motor activation) for the purpose of running through the a1800 codec encoding/decoding process to attempt to find out why these frames do not work.
I have isolated Frame 46 from Region 1 of ratadon3.bin -- it crashes immediately.
Here is the culprit Frame's hexadecimal
54 B1 69 04 A9 32 0F E4 26 D1 D6 41 D4 5A 98 52 3F 76 76 46 42 B0 36 52 43 EB B6 07 DA A3 21 18 D7 8F 7C 07 E2 8B 2B 8A
...thats it. That's the entire Frame that crashes the projector (at least one of the Frames that does).
- Figure out why this sequence of hex causes a projector crash as opposed to a sound.
