Bug with PSO v2 EP on Dreamcast

Hi guys. Nice to meet you. I am a PSOBB/GC veteran trying PSO DC thanks to Aleron Ives's awesome work on EP edition. However it seems that I've found a bug with it so would like to report it as detailed as possible.

1. Platform : Dreamcast (No emulator)
2. Disc : PSO v2 EP (Burned CD)
3. Difficulty : Hard
- If I remember correctly this issue didn't happen in the same quest with Normal difficulty.
4. Offline game
5. At the end of the quest "The Unsealed Door", fighting De Rol Le
- Well, I just found that this quest is super annoying in DC version with Mome doing nothing and killing himself over and over again. So I tried it with EP
6. Problem : Mome died. He was supposed to revive. However just right after his HP bar filled up fully, the screen stopped moving, with BGM still played continuously.
- Soft reset didn't work. Even opening the cap and removing the CD didn't change the screen. So I had to switch off Dreamcast itself.
- This issue happened 2 times for me.

I'd appreciate it very much if Aleron Ives has time to take a look at it. Thank you.

I haven't experienced that problem myself, but it's possible that DC doesn't like respawning NPCs in quests. For some reason the screen flashes black every time you spawn an NPC, which doesn't happen on PSO PC. I made the patch for PC, so perhaps it doesn't work as well on DC. Does it happen every time? If it happens a lot, you can always take the "classic" approach to that fight and just not play Unsealed Door until you're ridiculously overleveled for that difficulty, and then destroy De Rol Le before he has a chance to hit Mome.

Actually the "softlock" has happened during De Rol Le fight only (2 out of 2 times). So I assume that respawning NPC during boss fight does not work for DC... OK I will skip the quest for a while. Thanks.

I guess that's another minor difference between DC and PC. Thanks for reporting it. I guess that also rules out having Mome "play dead" during the fight, which is what Sega did on GC, since that requires respawning him, too.
