SGDK hardware

A ROM running in an emulator is a useful milestone, not console certification. Start with the reported symptom and an exact build. Separate a software defect, an emulator setting, a cartridge limitation and a physical console behavior before proposing a low-level workaround.

Establish the test environment

Record the ROM SHA-256, release/debug mode, container/SDK/compiler versions, console model/revision if known, region, display path, peripherals and cartridge or flashcart model/firmware. For an emulator, record its version and actual emulated system/region. Unknown fields stay unknown.

For Mega EverDrive Pro USB upload, use sgdk-project's bundled host client when that skill is installed. Default deployments to hard reset; soft requires an explicit user request. Keep upload/install success, launch sent, fresh SGDK startup and actual electrical power cycling as separate observations. This skill owns those console checks rather than a second upload implementation.
