PLS SEND A PIC OF THIS SCREEN TO US RST 38 AF:3210 BANK:01,8,E BC:4567 DE:89AB HL:C2E6 VIEW:C2E6 0123 4567 89AB CDEF >3210 7654 BA98 FEDC 0123 4567 89AB CDEF SP:CDFE VIEW:CDFE 0123 4567 89AB CDEF -3210 7654 BA98 FEDC 0123 4567 89AB CDEF STAT:C0 K1:7E IE:07 BUILD:0145 MODEL:01
Explanation of each field:
- RST 38
- Name of the error condition leading to a crash dump
- AF, BC, DE, HL, SP
- CPU registers
- ROM, RAM, and video memory bank switch values
- STAT, K1, IE
- Values of some I/O ports. K1 is KEY1, a port with an inscrutable name used to trigger a CPU speed change on Game Boy Color.
- The areas around HL and SP are scrollable. The arrow points to which 16-bit word is at the address in VIEW. The heavy and light arrows show which of the two is currently chosen for scrolling.
- The ROM revision
- Result of feature detection of emulator quirks
The background tile map is scrolled 4 pixels to help keep the information away from shadows that might darken the screen edges.
