The BRA jumps to $008052 if !UberASMTool = 0, and to $00804E if !UberASMTool = 1. |
|
| $00804D | 1 byte | Opcode | Not modified, however is used by Lunar Magic as an RTL for calling routines that end in RTS in bank 0 with a JSL via stack magic. So don't modify it. | |

|
| $00806B | 4 bytes | Jump (JML/JSL) | Hijacked by UberASM Tool 1.x. JML, jumps to the routine that executes global main code. This hijack has been removed as of v2.0. |
