Inverse text ROM patch

Post by zephyr »

Inverse Text ROM Patch v1.0

The Inverse Text ROM Patch (INVTEXT) program copies the BASIC 32K mode ROM and cartridge ROM ($8000 to $FEFF) to RAM in 64K mode (Map 1), and patches the ROM (in RAM) to enable a inverse text display. It can be used in combination with my "CLOAD Auto-Run Enable" (CLOADARE) program which I recently uploaded to the Software Requests section of the forums in a reply to the "d32.rom hack?" post.

Enter POKE&HFFDE,0 to switch to the original ROM mode (Map 0) and disable the inverse text display

Enter POKE&HFFDF,0 to switch to the patched ROM (in RAM) mode (Map 1) and re-enable the inverse text display.


The program requires a Dragon 64 running in 32K mode, or a Dragon 32 with a 64K RAM upgrade.

The included wav file (INVTEXT.wav) was created with Sara Burgin's Dragon Convert (DC.exe).
