Revision as of 18:36, 18 January 2023

Test ROMs that may be helpful for developing an emulator.

Forum thread: "Writing $4203 twice too fast gives erroneous result (not emulated)" - contains some tests for obscure multiplier behaviour, work in progress.

ROM	Author	Notes
gradient-test	NovaSquirrel	Test of CGWSEL to demonstrate inaccurate emulator behaviour.
Two Ship	rainwarrior	Comparing mode 5 + interlacing against mode 1 graphics.
PPU bus activity	lidnariq	Demonstrates all modes 0-6 on a single screen.
Elasticity	rainwarrior	Mode 3 techniques for improving color depth beyond 8bpp.
