Dreamcast Roms - Working list of roms and settings

spruce_m00se

I ran mine at a 1350 overclock, and with the standard ebay special heatsink it farted and overheated in less than two mins playing Q3 arena. I 3d printed a case for it to hold an 80mm fan right above the crappy heatsink, it holds low 50's whilst playing Q3 arena now, and sits at 40 in the menu. Previously it was at 75 in the menu without an overclock and just the heatsink with no fan.

@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.
