Hello everyone,
I spent most of the day trying to figure out why retro games downloaded through Tinfoil were no longer being installed. I use this feature frequently for older games, so it was quite frustrating.
At first, I suspected a Sys-patch issue because the games would download normally, but then get stuck on a black screen before the ROM installation process could begin.
One important detail is that all previously installed retro games continue to work correctly. The problem only affects newly downloaded games.
To troubleshoot, I performed a clean Atmosphère installation and started reinstalling my modifications one by one. After some testing, I found that the issue appears immediately after installing Horizon OC.
As a workaround, I created a separate boot entry in hekate_ipl.ini without the Horizon OC modifications. With that setup, retro game installations through Tinfoil work normally again.
At the moment, I switch between two boot entries: one with Horizon OC enabled for everyday use, and another without Horizon OC whenever I need to install new retro games.
I am posting this mainly as a bug report in case the developers would like to investigate it. Based on my testing, there seems to be a conflict between Horizon OC and Tinfoil's retro game installation process. Hopefully this information helps identify and resolve the issue in a future update.
