RetroEncounter

We have been really cool this weekend in RetroEncounter. I have met to Mekanaizer and Inditek and We have formed a awesome group Dreamcast&Emulation DreamTeam: Franxis, Puck, Fox, NeoBlast, Mekanaizer, Inditek, Dr...




We have had some time for speaking and thinking about our projects and comment next steps. Also we have tested our emulators for looking for bugs and points to enhanced. Like GENS/GENS4ALL:


Download a preview for Dreamcast HERE. I hope that Inditek will release it soon.

Also I have seen problems for loading BIN with DreamShell; I use a simple SD Loader hat I built for fast coding. I shared it HERE.

DCaSTaway RC-6 for Dreamcast

I have a debt to release the latest release candidate of DCaSTaway for Dreamcast (only released for Dingoo-A320), but I need some time for coding Dreamcast SD-Card support and fix the STOP bug of FAME that delayed UAE4ALL release.

The news:
- Dreamcast SD-Card support for savestates and diskchanges.
- Latest Dingoo-A320 new features: Fast load/save savestates with Start+L/Start+R, better sound and more compatible with MFP interrupts.
- Uses latest FAME Motorola 68000 core: more faster and accurate.

And now... MAME4ALL

Another new beta release of a old project, MAME Arcade emulator for Dreamcast:



It uses same romset but it has SD-Card support for loading roms and save config per game, implements a file cache for fast loading and uses latest FAME Motorola 68000 core and FAZE Z80 core.

A promise is a promise

I just released a new version of UAE4ALL for Dreamcast and Dingoo after we fix STOP problem in FAME, well, really STOP problem has not been fixed but we have reversed subversion revision that do this bug.



News in this version:
- 30% speed increased: Sound and Video render improved.
- Savestates support: The length of a savestate file is 200-300KB, so SD-Card is needed.
- Dreamcast SD-Card support.
- New option menu for screen position.
- Uses latest FAME Motorola 68000 core: More stable, fast and accurate.

SNES4ALL Beta-1

I just finish the new beta release of my SuperNintendo emulator for Dreamcast:



It has a very important speed increased and VMU/SD-Card support for Savestates and SRAM. At the future I want to implement a OpenGL/PowerVR tile rendering and assembler PPU code because I think that it is the way for avoid frameskip.

In the meantime... SNES4ALL

Fox and me are trying to fix our Motorola 68000 CPU core when STOP+Interrupt happens. I have located this bug and traced it using DCaSTaway but right now Fox needs some time for fixing in FAME/SH4 generator. Guru meditation? DCaSTaway and UAE4ALL releases are waiting this fix.

And now I can not stop, so I am working on SNES4ALL since a few days. The main work is to improve the Marcus Comstedt assembler code for CPU, the sound render and the tile blitters.

I have gotten freeing 2 CPU registers for other uses and speed up using pipeline slots and cache alignment. About the sound render, I have rewrited it using 6 different methods (ALTDECODE based) but needs tune it, and the tile blitters, I am coding (trying really) a new set of blitters for drawing block by block instead by line.

Also, now supports Dreamcast SD-Card for loading ROMS and savestates, but I have to able to write savestate support for VMU yet.

I did it !

Awesome! I have could speed increase (even more) for Dreamcast and Dingoo A320:




A lot of games run very close to full speed and also it support SD cards for savestates and load/save diskimages.

The secret has been disabling the redundant code and getting that it is processing (blitter and render) only exact lines to draw. This has been more easy to say and think than to do it. I have spent years to do it finally because the architecture of Amiga machine is very complex.

Now, I need some time for releasing it because we have found a new bug on FAME Motorola 68000 CPU core. I hope that we can fix it in a few days, almost before of RetroEncounter event at April 9th.

I really love this emulator! It is the most hard that I have worked on it.
