Beetle PC Engine libretro

Beetle PC Engine is a port/fork of Mednafen's PC Engine "pce" module to the libretro API. This core supports both CD-ROM² and SuperGrafx emulation.

This PC Engine module is more accurate than the Fast module, which trades away typically unneeded accuracy in favor of speed. Unlike Beetle PCE Fast, Beetle PCE retains built-in SuperGrafx support. SuperGrafx support can alternatively be found in the Beetle SuperGrafx core.

Features:

• Sub-instruction timing granularity (but greater than cycle granularity)
• All sprite sizes supported.
• 16-sprites per line limit emulated.
• Accurate HuC6280 flags emulation.
• Dot-clock emulation for more accurate aspect ratios.
• Support for Street Fighter 2's HuCard hardware.
• Support for Populous's backup RAM.
• 6-button pad emulation.
• Mouse emulation.
• Working CD+G playback.
