loader 0.7.0 только для HDD мода, SD карту он не поддерживает и никогда не будет

I think I found minor bug of Iso loader 0.7 beta1 (0.7.x_OPT-Only_noCDDA (beta 1)) When I played sakura wars3..
In battle mode of sakura wars3,If you select special attack(When red gauge is full ,It is possible to select special attack by pushing B button) and attack enemy,then battle animation scene begin to display.
When It begin to display character's face, If you press start button several time in order to skip this battle animation,It would rarely freezed..
I tested both of turnning on or off DMA mode in Iso loader 0.7 beta1,But It is impossible to fix this bug.

I found that this bug never happened when I played sakura wars3 with retail GD.

I think that this minor bug is something to do with async, Because I found that When I run Moekan with Iso loader 0.7 beta1, and push B or Y button many time in order to fast skip dialogue, It would suddenly freezed at any time in the middle of game play.But When I run Moekan with Iso loader 0.6.10 of below preset,It never freezed any more.
(0x8cfe8000,DMA on,SYNC 16,CDDA off,OS auto,Loader 11)
I heard that Iso loader 0.7 beta1 don't use Async ,DMA settings, So I think that This minor bug would be fixed if Iso loader 0.7 beta1 supports Async and DMA settings.

You can try with loader 0.6.11_se (or 0.6.11, if there is cdda)
With dma and Sync 16, or no dma Sync true.

There are some minors issue with 0.7 B1 and 0.7 B3 and not exactly the same ones.

I try those 3 loaders, in order to find the best config :-)

[chth96]

I have tried to find any preset in Iso loader 0.6.11,0.6.10,0.6.9 in order to run sakura war3,But It is impossible for me to find any preset in Iso loader 0.6.11,0.6.10,0.6.9.
It seems that the only Iso loader which is able to run sakura war3,4 is Iso loader 0.7 Beta1.

[fafadou]

The best memory for loader 0.7.b1 is :
0x8ce00000 do you have try it ?
Finally you can do with 0.6.11_se true dma with config for 0.6.10 you mentionned.

I always use memory preset of 0x8ce00000 for Iso loader 0.7.x beta1,2,3,
And Of course I run it(sakura wars3,4) with most of default memory address of Iso loader 0.6.11, 0.6.10, 0.6.9 and turning on or off DMA and tried most of ASync value(true,1,2,3,4,5,6,7,8,16).
But All of my trial was in vain..

I just have found that When I played sakura wars3 in retrodream It freezed (07:27) at the end of minigame which is included in Episode 8 and could not continue gameplay anymore .

I think that loader 8(Iso loader 0.7.x beta1) obviously need to update in order to fix this bug(sudden freezing (07:27) at the end of minigame in episode8)




If you are interested in this problem You can test it by downloading below link of vmu file which is compatible with flycast emulator and dreamshell's vmu manager and the same save data with youtube video

I don't know if @Megavolt85 and @SWAT focus on loaders again anymore even for minor update.

As you I have still suggests in mind that looks easy from outside like
try to do a 0.6.11 with no fragmented data as 0.7
a 0.6.11 version for wince games to see the cdda improvement.

and your well suggest to add async selection enable for 0.7.x b1

I'll keep in mind the genius @Swat's idea to put the cdda function at the end of memory and not the beginning.

But they give all they got already and go beyond what is humanly possible.
@Megavolt85 worked also fabulously on atomiswave games too.


It's uncomfortable for me to request more, and they deserve a break.
I can just hope they are fine due to the actual damn pandemic.

Of course we still can talk about the best config with great pleasure :-)
It's good to see an other great guy as you here.

[chth96]

all of my writtting is intended to draw attention in the hope of fixing these bug someday in the future.
I never intend to pressure or beg developer to fix these bug as soon as possible.
Although,I only have a very little and very elementary experience of C language and be terribly bad at programming,But I know that To find and to fix bug in programming is very irritating task. So It is not my intention to pester developer for fixing bug which I found.

and As for best configuration of iso loader,I think I made every effort to find best preset configuration as possible as I can. Basically I tried all of retrodream's address list in iso loader 0.6.11,0.6.10, if It was impossible to run targeted game in Iso loader 0.7.x beta1,2,3

[fafadou]

I know don't worry :-)
It's a good thing to write what that be "easily" done.
From my side, I know only very few C and assembler but I'm ready to help someone for improve loader as I can.
But I'm too bad, to look at alone...

If you use retrodream, the 0.6.11 loader is available only in 0.6.11_se version (without cdda).
Did you have try some things with 0.6.11 ide.bin "standard" loader ?

[chth96]

I added all file of Iso loader 0.6.11 (ide_alt.bin,ide3.bin which is included in isoldr_v0.6.11_beta.7z) to loader device of retrodream as number 15 and number 16.

But It seems that all of these Iso loader 0.6.11 have the same results respectively.

For example, If I succeed to run First Kiss Story2 in Iso Loader 0.6.11_se version(ide_se.bin without cdda) of below configuration, then all of other Iso Loader 0.6.11(ide_alt.bin,ide3.bin) also succeed to run First Kiss Story2 with below configuration,too.
(Direct,0x8cb00000,OS auto,CDDA false,DMA true, Sync 7)

But If I failed to run FKS2 in Iso Loader 0.6.11_se version of different configuration, then all of other Iso Loader 0.6.11(ide_alt.bin,ide3.bin) also failed to run First Kiss Story2 with different configuration,either.

I considered some of japanese game(sakura wars3,Moekan,pia carrot3) which have sudden freezing problem in ISO Loader 0.7.x Beta1.
Common point of these problem is that This freezing problem occur when I continuously press A or B button in order to skip dialogue or battle scene.
and When I tried Moekan, Pia carrot3 in ISO Loader 0.6.10 of below configuration there is no freezing problem at all.
(0x8cfe8000,DMA on,SYNC 16,CDDA off,OS auto,Loader 11)
I think that this freezing problem has to do with DMA and SYNC settings in ISO Loader 0.7.x Beta1..

I am using sd-card SanDisk 128gb class 10 A1 u1 and most of the games I use work pretty well including sonic adventure 1 and 2 using iso loader 0.6 just wondering if u will be updating the SD card to iso loader 0.7 cause

no, bootloader 0.7.0 uses the same reading mechanism as BIOS, SD support is technically impossible

[joxley192]

Ok will be looking into doing IDE mod then in the next 2 weeks I need a way to format my ide drives to fat32 cause I don't have a computer with a IDE port in but I have to say most of the games seem to work very well on sd-card I did have a problem with sonic adventure where it would mess up the videos and audio but I just downloaded CDI version and made it in to iso format and it now works with no problems by the way is there a way u can had homebrew to the sd-card so it loads of the SD card and not in iso or CDI

[joxley192]

Yes got my IDE mod done works amazing only got a 80gb harddrive for now but will be getting a bigger one soon love the fact I can play sonic adventure and other games with out having to listen to the GDI drive thank u for this amazing iso loader

Hi, I wanted to ask if the file should be replaced in the dreamshell isoldr folder and that's it?
I ask because I am distant from the console and I cannot make changes in real time.

edit: sorry seen now yes thank you

[fafadou]

I just finish resident evil 2 modding by green ranger, I used 0.7.x.b1, run like a charm

added:

[fafadou]

I'm sorry, my dreamcast doesn't run well, I'll try the games this evening but Shadow gangs has cdda ?
