Dreamcast Roms - Working list of roms and settings

@tmntturtlguy Mind sharing your overclock? Does v3d help at all with Dreamcast?

Ecks

Im using this one now which before i was using a normal type of case but wanted to do a little overclocking myself to see if certain Mame games works better you know.

@theWinterDojer here is what i am currently using as a fairly safe overclock with my heat sinks and fan. Please note, i have 3 separate retropie's. I have 2 in cabinets that I run without any overclock and I have 1 that I run on my TV that I use this overclock. When i get time i am going to try testing it out at 1400 to see if i can improve on a few more games and psp. As for if v3d does anything for dreamcast - i don't really know, but it does help on N64.

I originally had my over_voltage set at 3 but after playing N64 for a while I started getting some instability and freezes so i bumped it up to 4 and it runs nice and smooth.

#uncomment to overclock the arm. 700 MHz is the default.
arm_freq=1350
gpu_freq=500
core_freq=500
sdram_freq=500
sdram_schmoo+0x02000020
over_voltage=4
sdram_over_voltage=3
v3d_freq=525

@tmntturtlguy Sweet, I am running the same thing actually, except without sdram_schmoo and sdram_over_voltage. I haven't found it to be necessary but maybe I should give it a try and see if it helps.

Also, not sure if you copied this straight from your config but sdram_schmoo has a + sign instead of a =.

@thewinterdojer typing error!

@tmntturtlguy I was hoping it wasn't and you discovered a secret technique which made N64 and Dreamcast perfectly playable.

I've ran Sega GT, Sword of the Berserk and Soul Fighter through Reicast on a non o/c stock Pi3 and they played fine give or take any stuttering, so they should run more or less perfect on o/c settings.

@cornervizion SWORD OF THE BERSERK! how was the game? this has been on my "to play" list for quite a while.

Cornervizion

@buddyscott Hi, I tried it out the US version over Christmas and that played quite well. I didn't pursue playing any more as I was concerned about the Pi's temperature. But I'll be looking to o/c the machine at some point to try Reicast again.

Do any of you get the date time screen every time you play a dreamcast game? I've tried several bios files thinking thats the problem and its never resolved it.

TMNTturtlguy

@hurricanefan yes, there are several other posts on this issue. From what I understand The pi doesn't have a battery so it loses its time when you power off....there is more to it than that, but you can look it up in a lot of other threads.
