Release REICAST - Dreamcast Emulator

MrBazil2k · Dec 30, 2013

*DING DING DING* ready for round no. 2

:

same Setup of course: 1200 Mhz - SGX 4.10 - SZ 1.60

- Incoming : Fullspeed, nothing else to say

- Expendable : Fullspeed, nothing else to say

- Trickstyle : is still experiencing graphical issues, sometimes the character shows up now,

                    lvl design wont show up completely again, only a part of the arena is visible in the far distance (like before).

                    As I move the character/camera around parts of the lvl design are appearing and disappearing again.

                    Just found my way into the first race, sound working flawless there, but I cannot see a thing except the 2D lvl background =D

- Silver : Playable, but little slow as always, heavy sound stuttering like before.

- Re-Volt : 90-100% gamespeed (faster), sound is good, only a slight stuttering if there are all karts in one place (like before) , BUT still no menus.

                 I have also discovered another bug, with those 2 versions tested last time I was able to drive through objects like ramps or cars without

     any collision. (Switched back to the version from the repo : there the collision works like it should.)

- Dead or Alive 2 : 70-80% of gamespeed (experienced faster than before), although sound still stuttering during fight but less than before.

- MDK 2 : Fullspeed, still that texturing bug while in sniper-mode, parts of the gauge always faces the ground texture

- Rayman 2 : Fullspeed, missing some textures.

- Virtua Tennis : Playable, still a bit slow, sound stuttering

- Soul Calibur : Fullspeed, some sound stuttering left, but got reduced a lot by the last 2 versions of reicast

P.S. Going to post a video about this later... (Trickstyle, Silver, Dead or Alive 2, MDK 2, Rayman 2)

I don’t have access to a Mac to test it, but I found and attached (intel_osx_chdman0144.zip) an Intel Mac OSX build of chdman version 0144.

You most likely have to have to use it from a command line like the Windows and Pandora versions of chdman I posted.

$ ./chdman -createcd Skies1.gdi Skies1.chd

Thank you for your support. It works perfect.

I got this error with chdman for mac on OS X 10.9:

dyld: Library not loaded: @executable_path/../Frameworks/SDL.framework/Versions/A/SDL

Maybe if I install this SDL from somewhere it works.

But for now I am using WINE and its is working fine.

I'm on OS X 10.9.1 and my first tested game, compressed with chdman, works fine.

You need to install the SDL Framework 1.2.15. Newer one doesn't work.

You only must copy the framework to /Library/Frameworks

It's only 1.4 MB. You can find it here:

If you can test this new release and compare it the the previous alpha alpha

Tested both PNDs you posted today and they seem faster. The sound stuttering is slightly reduced. More sound effects can be heard than before.

I was having a problem with the runscript.sh not remembering file names with spaces and not selecting the previous file as you intended. So I made a few changes to runscript.sh to allow it to handle spaces in file names and automatically select the previous file.

The line changes are to 66, 69, 70, and 74. Here is the diff:

I attached the modified runscript.sh.txt. To test it rename it to runscript.sh (remove the .txt extension) and put it in your ...pandora/appdata/reicast folder

EDIT: Replaced hard coded path to "/mnt/utmp/reicast' on line 74 with the $pwd variable.

Very nice, I'll update the script for next release.

I spend most of the time on shad, shld and sbc, and I'm still not sure there are 100% correct (setpeq too).

Click to expand...

Hey, I don't know what method you used for shad and shld, but I came up with a nice method to emulate these in ARM once upon a time.

For example, in the case of SHAD Rm,Rn:

ANDS temp, Rm, #0x8000001F
RSBMI temp, temp, #0x80000020
MOVPL Rn, Rn, LSL temp
MOVMI Rn, Rn, ASR temp

For SHLD, of course, replace ASR with LSR.

Edit: Trimmed the quote

Nice one! I'll update my code

MOVPL Rn, Rn, LSL temp
MOVMI Rn, Rn, ASR temp

I added a couple of emiter, and the shad now looks like that

AND(r0, reg.mapg(op->rs2), 0x8000001F, true);
RSB(r0, r0, 0x80000020, CC_MI);
if (reg.mapg(op->rd)!=reg.mapg(op->rs1))
MOV(reg.mapg(op->rd), reg.mapg(op->rs1));
MOV(reg.mapg(op->rd), reg.mapg(op->rd), S_LSL, r0, CC_PL);
MOV(reg.mapg(op->rd), reg.mapg(op->rd), S_ASR, r0, CC_MI);

And calc84maniac, do you also have a good DIV algo?

Ah yes, of course, if it's not CC_PL, it's CC_MI, so op->rd will have it's value no mater what. Thanks for the tip, I'll update the sources.

All that ARM intruction+flags is new to me. I'm an x86 oldschool

Tip: If it's posible select 50hz tv output, some games have better sound that way (less stuttering).

Works at least on Shenmue 2 and Headhunter, wich are both not playable. Headhunter first level fullspeed but when loading seccond level reicast crashes. Shenmue 2 when loading Abberdeen after the intro part reicast crashes.

Ps: anybody got a WinCe game running? Would be neat to see Halflife running on Pandora.

itami · Dec 30, 2013

How do you disable music in reicast?

Only from ingame for now.

NoeleyC · Dec 30, 2013

Bomberman Online works, but you have to use the US bios. It runs a little better than the original alpha but it still very slow with quite a lot of graphical glitches

Fur Fighters - Slower than with the original alpha, also the sound effects aren't working in-game

Rayman 2 - works a lot faster in this version, but mine crashed back to desktop soon after starting playing (need to try it more though)

MrBazil2k · Dec 30, 2013

Short question @ itami :

What SGX Driver Version do you use ?

EDIT : same question @ stouffa

Hmm no crash issues for me, using my 1Ghz Pandora with SGX 4.10

Actually with some serious overclocking I can almost get rid of the sound stuttering.

Yup Yup, experienced the same here...

Soul Calibur runs really good at 1200 Mhz, SGX Version 4.10 and one of the newest versions of reicast here from the forum post.

Do not really know but isnt it even Fullspeed or at least close to it ? still with a bit of stuttering left of course. (and weird looking menu)

Hummm... that is strange, can you get Soul Calibur to work like in the video above ? maybe with less overclocking ? it runs quite good that way...

ptitSeb · Dec 30, 2013

Soul Calibur is my test game, I test improvement / regression mainly with this one, with the objectiv to have it FullSpeed with no sound stutering ... and it should not crash

Sorry but it find that slow.

My dreamcast is not hooked up right now, but I did find a real dreamcast vid on youtube...

ps: Soul Calibur did run on my pandora with the first version of reincast.

I found an error on line 69 which prevented directories with spaces from being recalled correctly.

Line 69 should be: cd "$(dirname "${CDFILE}")"

I edited the runscript.diff in the quote above (and in the original post) with the correction.

Thanks for working on this and all the other Pandora projects you have a hand in.
