RGB2RTG 0.5 Could Make the PiStorm Amiga's Two-Screen Cable Dance Considerably Less Silly
Astair86 launches RGB2RTG 0.5 for PiStorm Amiga setups, redirecting native RGB chipset video into the Raspberry Pi RTG HDMI pipeline to end the two-monitor shuffle.
Amiga 1200 owners using PiStorm acceleration have gained an experimental software tool that tackles a wonderfully specific modern-retro annoyance. RGB2RTG 0.5, developed by Astair86 and released through Itch.io, is an unofficial Emu68 fork designed to redirect the Amiga's native RGB output into the Raspberry Pi-driven RTG HDMI display path. The problem it attacks will be familiar to anyone who has built a heavily upgraded Amiga: RTG applications can appear beautifully through HDMI while original chipset games and demos still emerge through the machine's native video output. The result is often two cables, two display inputs and considerably more monitor-button pressing than Commodore engineers could possibly have anticipated in 1992.
RGB2RTG attempts to capture or redirect those native screens so users can move between Workbench-style RTG environments and chipset output on a single modern display. The current 0.5 version should be treated as experimental rather than magical replacement hardware, and projects such as the forthcoming Frame Thrower pursue related problems through dedicated hardware. Even so, it is an intriguing demonstration of what the PiStorm ecosystem has become. Originally attractive as an inexpensive acceleration route, it has gradually evolved into a playground where Raspberry Pi processing and classic Amiga architecture can cooperate in increasingly strange ways. We have apparently reached the stage where an Amiga's video output can take a software detour through hardware invented decades after Commodore disappeared. Perfectly normal retro computing, then.
