Shadow Hearts Covenant is hard to come by. As such fans uses emulators to relive playing the game or seeing what people are talking about. The thing about this is the emulator does have an issue with a visual bug that loses the background when the judgement ring comes up. This fix should help thanks to Fothsid on github.
Description of Changes
Invalidates local memory for render targets whose memory regions overlap with the requested one, instead of just checking for the same TBP.
Rationale behind Changes
Games like Shadow Hearts Covenant offset their GS downloads by specifying source Y coordinate that is beyond the texture size. Without this change, the game experiences semi-random rendering issues when displaying the Judgement ring in battle, as detailed in #3437. This PR essentially fixes that issue.
Suggested Testing Steps
While this PR fixes #3437, it could easily introduce new issues to other games, which is something that needs to be tested. For Shadow Hearts Covenant, enter a battle and try to attack/use skill or item, the game shouldn’t display any black screen or wrong shots when the Judgement ring appears.
