I confirm evil twin perfect in GDI Optimise

I have just Chuchu Rocket,South Park Rally and Sega Extrem Sports,I have no music sounds (just effect)

[dragoncity]

Hi,

Resident Evil 2 it's ok in GDI Optimise ONLY !

But there is IMPORTANT lag during cinematic...a solution..? Because I have tested DMA...and all memory (0x8c)...and CDDA...etc..nothing change.

Thank you

Ps: It's better when the game in launch with DMA..?

Of course.
Also MMU games (like WinCE) works only with DMA and only with ISO or optimized GDI.

[dragoncity]

OK but Resident evil 2 in GDI Optimized work only in defaut config,if you put DMA black screen every time...witch each memory...

This is my list if you want to test

Optimized GDI and ISO runs with true async DMA by default.

Hi,

For Chuchu Rocket in GDI (not gdi optimized,because with DMA black screen)
I can run just with boot "IP.BIN" and CDDA
But after with each memory I have freeze during the game... :/
So now I have music,but freeze.

For Sega Extreme Sports in GDI (not gdi optimized,because with DMA black screen)
I can run just with boot "IP.BIN CUT" and CDDA
But after with each memory I have freeze during the game... :/
So now I have music,but freeze.

So now I can have music with these games,but freeze during the game..a solution?

Thank you

Sega Extreme Sports works for me with CDDA and DMA on optimized GDI.
Try defragment/format your HDD.

[dragoncity]

With my friend "MoiGamerDuDimanche " we have the same probleme with these games...

It's sure,Sega extreme sports GDI OPT,if we put DMA..it's black screen...

So maybe an error when you have optimized...

I juste click on "optimize_gdi.bat",it's ok no..?

So for you,you click on the game..you go to setting,after you put DMA and CDDA...you save..you click again and it's ok..?

I checked it right now.
Optimized GDI of US version, true DMA, CDDA, 0x8c000100 - works great.

[dragoncity]

Thank you for your answer.

I have the answer !!!

Sega Extreme Sports...So in PAL..doesn't work !
But Xtreme Sports..So in US... works with your config ...
I have a freeze..right now..erf..during the loading.. :/
Finally,for me the best is with GDI "no optimized" and CDDA

Ok now..Chuchu rocket...pal or us..i have freeze during the game..it's random...:/
Gdi or gdi optimized it's the same problem....

Can you explain what is the difference for the memory (000100...004800...)it's the region..it's what..?

And Emulate async... 1+ 2 3 4 16..etc..it's for what?

Boot mode..direct..ip.bin...ip.bin cut what is the difference..?

Because We test but we don't know the consequences

Thank you

Memory used for the loader. In most cases 0x8c004000 it's normal (also 0x8c000100 works in 50% games). But some games used this area, so need place the loader in another memory.
Emu async need only for PIO mode or DMA with CDI or not optimized GDI (or for SD with any images). It's emulated async reading as true DMA, for more smooth gameplay if the game preload data continuously in gameplay. Lower value - more smooth gameplay, but long loading time and vice versa.
Boot mode in most cases use - Direct. Some games need boot from IP.BIN, but IP.BIN used the same memory as loader, so in this case can help truncated IP.BIN. If you place the loader in another memory, you can use full IP.BIN. But really in most cases works Direct.

CDDA used additional memory for PCM buffer, if you put loader to lower memory, buffer used high memory and vice versa.
If you boot WinCE and use 0x8c000100, in this case PCM buffer will use 0x8c008000 so it's should better compatibility. Also this trick used for ADPCM tracks, because for it need buffer in twice smaller.
In another cases if you put the loader in lower memory (0x8c000100 - 0x8c004800), PCM buffer uses 0x8cfe0000 (because KATANA used some lower memory all time unlike WinCE) and it's can give some problems. If you have problems with CDDA, try put the loader in some high memory, that place the PCM buffer in lower memory and you can play with high memory for search free space for the loader.

Perfect,thank you !

For remove gdrom (pcb),I can link P096 to P154..but there is bug apparently.



So I bought active crystal 33.8688 MHz.
http://fr.aliexpress.com/item/Into-the-a...01903.html
how I can connect it to the point P096 (B23)..?

For finish,If I use boot_loader_devkit.bios or boot_loader_devkit_nogdrom.bios..what is the difference..?
It's better when we remove gdrom..?

Thank you

Without GD-ROM need use *nogdrom.bios, because retail bios firmware tried initialize gd drive.

OK Swat.

1-Chuchu rocket,it's work for you?
Just test one level (menu ...start start start....)

And if you have freeze tell me

2-When you optimize your GDI,do you use "raw2adpcm_ffmpeg.bat" or "raw2adpcm_g723.bat"
Because I saw people use it,but for me it doesn't work..the batch close immediatly..so it is important?

3-For the game "carrier" with GDI Optimized,sometimes I have freeze,it is VERY rare,but there is..and with GDI "no optimized" nothing..is strange..no?

I also had trouble starting Chu Chu Rocket , i tested various configurations and no got nothing (as with Radirgy and I have a Dreamcast JP ) I also found a problem with the Dead or Alive 2 Limited. This starts and random crashes and press START and selection menu pad Analog go crazy.
I am investigating the matter.
Swat what is the flag to enable fast load?

[dragoncity]

I saw on the other topic that Fast load change nothing

I'm clear with that but I occupy a custom interface that games start with the preprogrammed commands:
Example : < / input>
<Input type = "button" onclick = " os.execute ( ' isoldr /ide/Dreamcast/ISO/Dead_or_Alive_2_Plus.iso -a -f ');" Normal = " SLCTN " highlight = " SLCTH " pressed = " SLCTP " disabled = " SLCTD " x = " 313 " y = " 295 " width = " 56 " height = "19" >
<Label width = " 56 " height = "15" x = " 0" y = " 0 " size = "6" font = " Dreamcast " color = "# ffffff " text = "run game" / >

[SWAT]

Convert RAW to ADPCM need only for SD! Because it's slow. For HDD/CF use original tracks.
Fast boot - just disabled info on screen at loader startup. Little faster game start, nothing more.
