open_agb_firm gba_db.bin Builder v2.0 and other changes
open_agb_firm gba_db.bin Builder: * Updated to v2.0 * No-Intro DAT support * Additional entry support * Entries added/skipped are now output * Other optimizations Other changes: * Remove most overrides in `open_agb_firm.c` to prepare for gba_db.bin * Add `resources/gba.dat` entry to gitignore

# This script parses MAME's gba.xml (found here: https://github.com/mamedev/mame/blob/master/hash/gba.xml) and converts it to a gba_db.bin file for open_agb_firm.
|
||||
# This script should work with any updates to MAME's gba.xml, unless something this script expects is changed.
|
||||
# No-Intro's GBA DAT is also used for filtering and naming (found here: https://datomatic.no-intro.org/). The DAT should be renamed to "gba.dat".
