open_agb_firm alpha build 2020-10-26

This is a build from the kernel_experiments branch for the impatient.

• 8fdc74a A temporary workaround has been put in place to prevent panics using bootloaders with incompatible screen init.
• 07f6f01 Mimic ROM out-of-bounds reads more accurately (may fix games relying on it) including mirroring needed for the Classic NES Series games.
• 179ea50 You can now dump the GBA frame texture (pre-GPU processing) to "texture_dump.bmp" on the root of your SD card by pressing Y.
• ac33d98 Fixed broken file browser sorting.
• c87769a open_agb_firm now remembers the last dir you launched a ROM from.

This can and will destroy savegames for a few games due to broken save type detection so backup your saves! You have been warned.
Also note that EEPROM savegames from some emulators or even flashcarts are incompatible because they are laid out wrong (every 8 bytes block of data is reversed). This tool can fix that.

In the archive included are 2 builds. One with BIOS intro and one without. The used scale matrix is the default "Sharp interpolated" one.
