Prototype Fragments

There are many tiny fragments (especially at the ends of ROM banks), but this list uses only the largest found chunks necessary to recreate the prototype ROM bank.

xx8000   xx9894   Nothing yet found for this range
xx9895   xx997F   Fragment found at ROM offset 1B1895-1B197F, matches up to ROM offset 001CA4-001D8E, contains two differences
xx9980   xx9CDA   Nothing yet found for this range
xx9CDB   xxD95F   Fragment found at ROM offset 099CDB-09D95F, matches up to approx. ROM offset 002054-0066B6
xxD960   xxDABF   Fragment found at ROM offset 095960-095ABF, matches up to ROM offset 0066B7-006816, no differences except address shifts
xxDAC0   xxDE4D   Nothing yet found for this range
xxDE4E   xxDE7F   Fragment found at ROM offset 0BDE4E-0BDE7F, matches up to ROM offset 006BA3-006BD4, no differences except address shifts
xxDE80   xxDED0   Nothing yet found for this range
xxDED1   xxDEDF   Fragment found at ROM offset 0B5ED1-0B5EDF, exact match of ROM offset 006C26-006C34

xxE24F   xxE29F   Fragment found at ROM offset 0F624F-0F629F, exact match of ROM offset 006FA4-006FF4
xxE2A0   xxE94D   Nothing yet found for this range
xxE94E   xxFFFF   Fragment found at ROM offset 04E94E-04FFFF, matches up to ROM offset 00????-007FFF. Mostly UNUSED SPACE, some jump address shifts near very end and cartridge header differences

Differences

1B1895-1B197F Fragment

• Operations were swapped in two separate subroutines. Why? Good question.
