ES-DE's findEmulator() decides found-vs-not-found from the <command>
string's emulator token, and every real %INJECT%=...esprefix example in
ES-DE's own shipped es_systems.xml (Dolphin/PrimeHack/Triforce/Supermodel)
pairs it with an %EMULATOR_X%/%CORE_X% placeholder, never a literal path.
The previous ti994a <command> used a literal "/bin/bash -c ..." after
%INJECT%=%BASENAME%.esprefix, which ES-DE reported as "emulator not found"
even though /bin/bash obviously exists on the container.
Fix: give ti99sim-sdl a real custom_systems/es_find_rules.xml entry
(TI99SIM, staticpath ~/Applications/ti99sim-sdl) and reference it via
%EMULATOR_TI99SIM%, matching the pattern every built-in standalone
emulator uses. %STARTDIR%=%EMUDIR% replaces the old shell "cd && ..."
prefix to keep ti99sim-sdl's working directory at its own install dir,
where it looks up the console ROM via a plain relative path.
