What software to use to create the Dreambor 6.6 iso for Dreamshell? I have no sucess in create the iso ...
The old versions that has 1ST_READ.BIN i had no problem , but the newest that has dreambor.bin
my iso doesnt work for me.

Just rename it and delete the ip bin isomake tools same as normal
You think dreamshell could boot it not being called 1st_read.bin i guess not real hardware does as i have the custom ip.bin pointing to that name..
Rename to 1st_read.bin use a normal ip.bin use iso make tools from dcswat

make sure to ether convert gif to png compression to save ram and to pal swap it back to 8bit color or 256 colour it's a 30fps change..
Also convert all ogg files to bor format as it is straight wav to the acia no decoding like ogg has to do can bring fps
quite a few tricks to make the 8bit colour look just as good as 16bit pal and have up to 60fps smooth..
Takes work converting all the files but you can save 40% ram use-age
Also what you put in the levels text if there is no next it loads all in memory in the scripts best to use next or break things in to 1 to 4 5 to 6 etc..
i will be adding proper unlocking saving to the vmu and optimizing sh4 math memory routines..
current version now uses vram and double buffering for faster access unpacked to the data folder it's 10 to 30 sec
packed it's well over 5 mins on a cdr ... also cached has to read the files 2 times 8 files each on boot and blocks loading... so always unpack to the data folder also uses less ram on boot and in the game.. No buffer holding and unzipping the big huge file..

6.6 low memory use 1mb bin it was 1.6 custom optimized sdl i worked on chui's sdl to make it faster
Now with sh4 math moop dreamhal replacement for memset and memcpy
Cdr gdemu test old was using 4mb on boot this using 2mb on boot..
load {name} {bi}
Used to load a model whose name is {name} in current level.
{bi} determines if model stays in memory or not after current level ends.
0 = Nothing. The model is left alone (IOW, remains loaded) and loop moves on. This is the default action.
1 = Unload model only. The model is unloaded, but the sprites are not. Pretty pointless unless the model has a lot of script attached to it.
2 = Unload sprites only. The mode remains loaded, but its sprites are removed from memory.
3 = You'll notice there there is no third option, but because bitwise logic is in play, 3 effectively means "1 and 2" - model and sprites are unloaded.
This command is for loading weapons models or other entities which shouldn't be loaded until this command is executed. It's useful for memory usage control.
Don't forget to load {name} with 'know' in models.txt!
Like other level objects, this command must be followed by 'at' (see above) and also counted by 'group'.
spawn {name} {bi}
{name} is the name of an entity defined in a .txt file which was loaded in MODELS.txt.
{bi} determines if model stays in memory or not after current level ends.
0 = Model stays in memory.
1 = Model is unloaded when current level ends.
{name} will be spawned (created) in current level. Where and with what attributes are determined by the next set of fields.

Hi Ian! Thank you for your hard work on this. The least I can do on my part is give you a report of what I have found so far:
1.- Indeed there is a slight increase in FPS but there is a significant performance loss when using transparent layers at full screen size (example 320x 240 rain sprites)
2.- There is also a loss of performance when using the perspective or wave effect in the sprites (using these commands you lose up to almost half the FPS)
3.- Using higher resolution apparently it becomes more stable and fluid but you automatically sacrifice about half of the FPS (from 30 FPS to 15 FPS but with less instability) apparently something was gained in the same way.
4.- An error in the "Start Game" menu if you go up from here the engine restarts.
5.- Animated GIFs continue to play relatively slowly, even with a small speed increase.
Outside of this I see that there are enormous possibilities of getting this to work at 640x 480 since I notice less drop in frames than with 320x 240 which is more unstable even using the effects of scaling, waves, alpha, perspective, etc ...
PD: I think the friends of Team Senile must have the answer to the increase in performance at the graphic level since they achieved it with the "Intrepid IZZY" engine that runs at 60 FPS and at a resolution of 640x480.

16 and 32 colours might have those problems I will work on the full screen trans i have something for that soon it should really help..

Going to working on somethings for full screen trans.. As for unstable i play thru 5 openbor mods i repacked with out a problem with the start menu on my youtube channel I will take a look at the build i uploaded here maybe it's not the same as i used 16 or 32 are slow 8 is 50 to 60 fps right now
wanted to take a look
These are all running on dreamcast hardware not emulators
I have more to come your best bet is to pal swap to 8 and redo your game to get full screen 50 to 60 fps trans at the moment
