[DARKGATE]

DEAR BUCANERO, thanks for anwered me, now is more all simple, i have made questions, and the questions, i can made at you, wich have create this program, if you don't answer i repeat my question all right?

My temper is good FRIEND if you had problem with me, sorry much, i think wich you think bad on me, bah.

P.S. accept of learn C/C++ or SH4 if you can locate a good book or site for start
thank you.

Any updates here?

I'm almost done with the VMZip idea you gave me... Let's say its about 97% complete.

I'll try to have it finished & released in the next week, provided that I can get some free time to code the last details...

Good news!

I'm just trying to make something similar for Saturn using libbzip2.

I'm using bzip2 too! I don't know if my source code might be useful for your Saturn app, but if you want I can send it to you right now, even if its not finished yet. Let me know !

c ya!

I got very far with my Save Game Manager for SEGA Saturn. I almost thought I could release it today, as everythings is done, but my debug cycle takes too much time.

The virtual drive approach is amazing!
On Saturn, you have a lot of different storage devices: CD, internal backup RAM, cartridge RAM, serial (floppy) device and arbitrary amount of virtual drives. I made a wrapper around it, allowing EVERY DEVICE to be compressed into one file and automatically saved to every writeable device, including virtual drives...


BZip2 consumes a lot of memory. So I made a custom memory allocator and use blocksize 1 for compression. Nevertheless, I'm in need of a better memory allocator(which uses multiple memory regions) to avoid crashing when doing things which require more mem.

Though using weakest compression efficiency, first tests did compress to 50%. Sure this is not a representative value.


On Saturn, we already got a file copy tool, but this one is much better. It's been designed for efficiency in handling it. Inspired by Norton commander, too.

You see, I'm quite excited about it, hehe.
See you!

BGET is really an awesome memory allocator!

I use it to allocate memory in up to 5 different regions on Saturn!
The external RAM cart now allows to take a better compression.

The effect of compression is really cool: some files (racing game replays...) are 2x as large as the internal backup memory and do only fit into the external backup cartridge. And even there is only space for a few of such files.

Using bzip2 compression, I can place about 5 of these files into internal memory. That's a great difference.

I just found a memory leak today, so I'll release it tomorrow.

No sbi version for this?

Thanks to Hashmire420, a .SBI version of my VMU CD v1.3.0 is now available.

I've uploaded it at my SourceForge.net project site, and here's the download link:
