Dreamcast load issue

[SsssQ]

after perfect crt setup I decided to play some dreamcast games. I had some gd-rom rips taken from cdromance and one ripped from my own gd-rom. here's the list of games i've got: sonic adventure 2(Echelon. my gd rom rip), puyo puyo fever(DCRES, CDromance, chd), puyo puyo 4(CDromance chd). I started puyo puyo fever, but when audio surround logo apperars I saw some graphical issues(some unknown shards of color yellow and green) next the most of the game's intro was missing textures and title screen was black. when I tried to go into menu the emulator crashed. after this I tried sonic adventure 2. the game functions as normal but when it tries to load a level it freezes, but you can exit from it. And puyo puyo 4 was played as normal(no issuses). Please fix the issue, who also got the same problem write in comments. I've got RPI3B+.

@ssssq also got enter key issue(but that's not your problem )

@ssssq you DO realise that N64, Dreamcast, and PSP emulation on the Pi is still far from perfect, and LOTS of games still do not even load, play properly, or crash?

This is nothing to do with Recalbox, but, the actual emulators.

With each update, more and more games do work (look at how many now work compared to just 2 years ago), but, you have unrealistic expectations.

Also, for all 3 systems mentioned, you really are best to have a Pi4.

some dreamcast games.

some graphical issues

As already mentioned, N64, Dreamcast and PSP are consoles that don't have perfectly optimized emulators for RPI, the best emulation happens in RPi4 (which is the most powerful), but even so users use overclocking to have a more fluid performance.
The graphical problems you have are normal, as the emulator was configured to have the best possible performance, and that's why it was necessary to give up the graphical quality: it's better to have a game that works, than a beautiful game that you can't play .
You can try overclocking if you're interested (and only if you have a good cooling system - never overclock without heatsink and cooler), but I don't know how feasible it is for you, you'll get a performance boost, but still it won't be a perfect emulation.

@zing when I was on HDMI it was running p e r f e c t. No lags. No anomalies. But when I switched to crt the troubles started.

after perfect crt setup

First: It would save time if you had said this information from the beginning, please specify as much information as possible so that someone can help you correctly.

So the problem is probably the fact that you configure it in CRT, possibly you need to change the Dreamcast videomode, and once again I would point out that Dreamcast/N64/PSP are emulators that have these emulation difficulties.

Let's go to some questions:

• Do you have your BIOS perfectly recognized in the built-in BIOS checker (green thumbs)?
• Have you already tested it with the two emulators: Flycast and Reicast?
• You can test the same game with an iso redump as mentioned in the documentation?

In addition, there is the question of the videomode I mentioned, the information appears in the recalbox.conf file:

## Dreamcast emulator
## Like N64, such a CPU intensive emulator needs a small resolution
## Consider DMT 4 HDMI (640*480) or DMT 9 HDMI (800*600). If you have a black screen on dreamcast, try DMT 9 HDMI here
;dreamcast.videomode=DMT 4 HDMI

The official Flycast documentation specifies some resolutions:

Reicast's official documentation specifies some possible video configurations:

@Zing anyways, recalbox sux, it did eat my entire 16gb sd card

@SsssQ , I really don't understand what's the problem.. Recalbox does not "eat" disk space for pleasure.
Without more information, we could not help you.
