Dolphin emulates GeckoCodes by fiddling with the CPU state when a VI Interrupt occurs. The problem with this is that we don't know where the PC is so it's non-deterministic and not necessarily suitable for use with the codehandler. There are two options: Patch the game like Gecko OS either directly or using HLE::Patch, or use a trampoline so we can branch from any PC even if it would otherwise not be valid. The problem with Gecko OS patches is there are 10 of them and they have to be configured manually (i.e. Game INIs to would need to have a [Core]GeckoHookType property). HLE_Misc::GeckoReturnTrampoline enables the Code Handler to be entered from anywhere, the trampoline restores all the registers that had to be secretly saved to the stack. |
