Bugs Also in the Original

In the following you will find a number of bugs which actually already occur when using the original interpreter / .EXE. That is, those errors are bugs in the games themselves, not in ScummVM. Still, we sometimes are able to implement workarounds, meaning ScummVM at times works better than the original ;).

Note that neither of these lists is complete.

Not Yet Fixed

Features

• Finish Apple IIgs sound support
• Better compatibility. NAGI is known to be more stable

Future

From Sarien Bugs and requests

Not Yet Implemented

• Hercules mode (?)
• CGA RGB rendering mode FR #438410
• Mac mono mode (?)
• Finish Apple IIgs music support

Implemented

• MIDI music FR #439547

NAGI features

First thing to consider is that NAGI has X11 license.

• Hercules fonts (suggestion is at Sarien FR #607641)
• Check Tandy emulator
• Apple II palette

Features that'd be nice to have

• Custom 256-color palette support for fan games using AGI256 or AGI256-2
  • This needs custom palette defining, loading and changing support as AGI256(-2) currently always uses the default 256-color VGA palette
• Custom picture/view/cel-dependent palettes
  • Example: Darken the backgrounds, lighten the ego and objects.
• Accurate white noise emulation for PCjr sound
  • Information about the PCjr's sound chip (Including white noise generation):
    • John Kortink's SN76489 reverse engineering effort
    • Texas Instruments SN76489 notes
    • Wikipedia article on Texas Instruments SN76489

Completely Wishful Thinking

• Support for AGI v2.001 + v1 PC-Disk images (The biggest bar to entry is really working out how the executable knows where files 'map' to on disk, the file formats are the same, so it is just working out how the game knows Sector X, head Y, Track D is the start of File Q).
