While neither the North American, nor Japanese release of (T&E Virtual) Golf has physical save hardware, the latter does support saving, when played in emulators or on flash carts with SRAM on-board. The game checks whether the SRAM is available and functioning correctly and if that check is successful, enables a full save setup, including freeing up the preset default slot. However, if that check fails for any reason, the game falls back to the password system.
Conversely, the US version has had saving disabled in the ROM itself, with the SRAM check hardcoded to fail. This patch restores saving in the US version by porting the hardware check from the Japanese release. The rest of the saving code was left completely intact in the US version. Also allows to erase saves with the normal in-game menu under “Individual Records”.
