VirtualBoy Recomp Gets Its First Title: Mario Tennis

No public disassemblies, no scaffolding: Mario's Tennis brings the Virtual Boy into the fold on the recompiler's own strength.
This post announces the Virtual Boy recompiler's first commercial title, Mario's Tennis. The platform choice is a deliberate inversion of the NES strategy. Earlier ecosystems targeted games with good public disassemblies; the Virtual Boy has essentially none. It was picked anyway, because the system itself is simple enough that the recompiler could work without that scaffolding.
That makes the project a useful stress test of the whole approach. If static recompilation only worked where the community had already done the reverse engineering, it would be a repackaging tool. Getting a commercial title running on a console with no disassembly heritage argues it is something more.
The post closes with a striking ambition: since the games become native code with a modern renderer behind them, the author wants to eventually visually enrich Virtual Boy titles beyond the hardware's red-and-black display, something no amount of emulation accuracy would ever offer.
