Description

In Phantasy Star (UE) (Rev 3).sms (verified good ROM, MD5:1110938DF80F4E44C8213D7F85CFB5E6), BizHawk 2.8 shows part of the sprite of Odin in front of the sprite of Alis, when it should be behind it. In BizHawk 2.7 it is OK.

Research direction

Reproduce the regression in BizHawk 2.8 using Phantasy Star (UE) (Rev 3).sms with the listed MD5, then compare the same scene in BizHawk 2.7. Start by tracing the SMSHawk sprite display and layering behavior around Odin and Alis. Done means Odin is rendered behind Alis as in BizHawk 2.7.
