ISO Loader 0.7.x Beta

[MannyMania]

Hi all, I've just finished my Dreamcast mod adding a CF Reader as slave. It load cdi images from a real 8gb Card just fine. Getting a real 256gb or 512gb CF card is expensive, so I tried a CF to microsd adapter with a 16gb microsd card and it won't boot. The DreamShell boot loader v2.4 screen says:
Checking for G1 ATA devices...
g1_ata_scan: found device with LBA48: 2051786407
936
Checking for SD Card...
It then goes to the DreamShell boot loader v2.4 screen with the Boot from RAM or CD options.

I also tried a 8gb Micro SD card in the CF to microsd adapter. The LBA48 message was different and it didn't work either.

With the real 8GB CF card that works, LBA28 is displayed and it detects the FAT32 partition 0.

Is there a newer bootloader version I can use?
Do I need to use a specific CF to microsd adapter or is it just not compatible with a CF to microsd adapter?

Thanks Guys!!
MM

Hi: How can we add more roms at the Emulators in GDI format ?

I tested all those from my CF card and didn't have any issues. All work great. Ooga Booga and the NFL games are the only games that have freezing issues for me. There's something specific about those games that causes an issue with CF cards apparently. I don't have a SATA adapter or an SSD so I can't test that.

I have tried Soul Calibur and finished the game and all works fine, the version that i have played is "Soul Calibur v1.000 [4S T-1401N]" in GDI-Opt (in a Dreamcast NTSC)

have you guys tried this item connected to an ide to sata adapter set to slave?

[fafadou]

I saw something like this a few time ago, it works but not sure this one does.

In order to use modern SSD for all games, we are still looking for IDE to SATA converter that can run visual concept games unfortunately...

all this adapters don't support LBA48

[fafadou]

I'll find an IDE hdd at home and I try to run ooga booga and TomJam&Earl 3 with loader 0.7.x beta 3.
I have an error message : "your IDE don't support LBA 28..."

What can I do for avoid this issue please ?


else I just saw there is a new gcc 9 version, is it possible to try it with actual loader as @SWAT has done with 0.6.0 loader from gcc5.2 to gcc 7.1 ?
Probably not compatible, just an idea seems that fast to try.

your HDD don't support LBA48 commands
all hdd 160GB and more 100% have support LBA48

most of the code is written in assembler, the new version of gcc won't change anything

[fafadou]

Do you have any idea why the 0.6.0 loader with 7.1gcc gives a better result than "standard" gcc one ?

0.6.x writen on C with small part writen on ASM
0.6.x syscalls used as function, original syscalls and 0.7.x work as thread
0.7.x and original use memory 8C000000-8C004000, for 0.6.x need more memory
gcc 7.1 crete comcact code and it's fine for 0.6.x, but 0.7.x very small and economy memory don't need
0.7.0 b3 has a cheat engine, but it did not go beyond the size limit

[Mu.]

Will there be any chance of CDDA being supported in a later version or is there some kind of limitation with the 0.7.x loader that won't allow it?

[megavolt85]

only one limitation, need research IDE->SPU DMA channel
the technical documentation says that such a channel exists

Maybe it's the same issue than skies of arcadia intro...

Thank you for response, It was the preset!, I have 0.7.Loader and 18 Wheeler in GDI OPT and CDI and both the same freeze at 4th phase. I found that the correct preset is 0x8CFE0000...,

now both CDI and GDI Opt works fine!, so I deleted the GDI opt in order to save HDD space

[fafadou]

@Dragoncity please update your list ;-)

I am having the same issue in HDD IDE (western digital 80gb) but only in few games now like NBA 2K2 AND NHL 2K2, message "LBA28 HDD not supported, can't init IDE" strange thing NBA 2K works fine but 2K2 no or because one is in 80gb hdd and the other in a 160Gb?. So I have a 160Gb IDE , could these and all ames work in it?
Dragoncity's PAL presets list are not all the same for NTSC Consoles?:
Some games like next one are different:
In my NTSC Dreamcast USA: NBA 2K working is
NBA 2K V1.008 [9S] : preset 0x8c004800, DMA On, Sync True, Loader 8, no Cdda WORKS! (Not 0x8ce0000)
If I am not wrong in these PAL/NTSC differences someone will have to start a NTSC Compatibility list for Dreamcast NTSC

[fafadou]

You must try it also depend of the brand.

preset 0x8ce0000 is a megavolt advice if I remember well, probably memory preset 0x8c004800 is good in PAL console too.

You can have minor differences between region but very minor.

You have add a cheat engine in the loader ! Each time I ask you to explain me something you impressed me ^^ What the purpose of this add please ?


As many dreamshell lover I hope a new loader with cdda, we waiting since so long.
At least :
An 0.6. equivalent with cdda via PIO in order to enjoy with HDD mod like 4 wheel thunder and suzuki all star racing because Actually you must use SD mod to enjoy CDDA.
A cdda loader little update for 0.6.x or 0.7.x with loop issue like you have briantly done for 0.7.x, to enjoy revolt with cdda.
Maybe a 0.6.x with cdda PIO and loop issue is enough to enjoy those games.
And of course in my biggest dream a complete new loader with cdda :

Mode, gdemu and USBGDrom builder must have the issue for this. May it's possible for us to ask them directly ?
Don't hesitate to request us if we could find some informations for you.
I just tried to do a google research and it suggests me to search SPI and not SPU...
Are you sure it's SPU ?
I found a document that is mention DSPIC33 it's the good dreamcast bus name ?

Of course, find time and energy for loader is luxury, I know it. I don't want to bother you :-)


A lot of posts are in russian about your fantastic adapter for mapple, I'm note sure ; did you have finish the project as you want ?
I follow also the obscure gamer forum.
It's a wonderfull work, I really wish to congratulate you. Be sure I'll try to build one.

i'm add codebreaker engine to loader, but need write new isoloader app for add/edit cheats

no, all ODE use hardware player
for HDD need write software player

yep
Sound Processor Unit - in dreamcast is AICA
look §2.6.2 Types of DMA in this dcumment

no, i'm alredy connect GameCube controller
now need fix problem with VMU emulation, it's work not for all

[fafadou]

Thanks for answered and share the document

As you said the document at §2.6.2 :-)
ARM Data DMA -> Transfers programs and data from system memory to ARM (sound processor)

I have look in the document :

I understand better why @SWAT told me about AICA too.
The document gives the adresses :
0x00707FFF -> AICA- Sound Cntr. Reg // in G2
0x005F780 - 0x0071000B -> AICA- RTC Cntr. Reg
0x00FFFFFF -> AICA- Wave Memory

The Wave memory is the 2 MB for cdda ?

And in "§4.2.2 AICA : The AICA chip controls the sound system" as you said :-)
and if I understand well the data flow is "PCM data format: 8-, 16-bit linear/4-bit ADPCM (ADPCM is a proprietary format established by
YAMAHA)"
ADPCM bus.

and finally there is a blueprint at §4.2.2 AICA :
"The chip configuration and connections with peripheral devices are illustrated below.
Fig. 4-1 Internal Block Diagram of the AICA"

There is a "path" as you may call "channel" from GD ROM

(17.08.2020 03:40)megavolt85 писал(а):  only one limitation, need research IDE->SPU DMA channel

Yes it is
There is an access procedure §4.2.2.3 Access Procedure
But I guess there is no IDE -> SPU DMA channel...

I practiced a bit IDA software but
If you just tell me where the CDDA is managed in the sd iso 0.6.x and in hdd loader 0.6.1_7.1gcc, I can try to import the CDDA mod from sd to HDD loader in order to have a better compatibility with HDD.
And start to understand how you have done and trying to help.
As you wish. as I said I don't want to bother you.
Of course I'll create a topic. i'm sorry to do off topic here.


Else I'm just seeing you have done a release of FX unit Unit in your GDI rebuild list. thanks a lot.

Цитата:GD-DMA is used to transfer data from the GD-ROM to system memory or to wave memory (AICA Memory).

Цитата:GD Data DMA1 Downloads programs and data from GD-ROM to system memory
GD Data DMA2 Transfers waveform data from GD-ROM to wave memory.

need GD Data DMA2

0.6.x use another method, he read data to system memory, split left/right channels and send to wave memory
for 0.7.x need another way:
1) rewrite batch optimisator (need split left/right channels on PC)
2) use GD Data DMA2 for reading direct from HDD to wave memory
