Dynarec is a LV2 patch system first implemented by AerialX which in a nutshell, allows for more power to be used by the PS3. This additional power can be used to run a wider range of applications such as demanding emulators like those for the Nintendo 64 and Dreamcast consoles. Dynarec never really saw light after 3.41 because future firmwares were never prepped to take advantage of the system. Here's what Blackdeath from the team had to say:
Kammy in 3.41 patched lv2 to execute a recomp dynamic code (knowed by many devs as Dynarecs).
In 3.41 even was contemplated the creation of a dreamcast emulator but this was stepback hence this type of things limited so many devs, but in the case of Kammy we had the possibilty to debug and easy recieve Printfs by net with socat. Having a plus of executing too JIT code.
This video shows how MA356 supports the new and renewed system of Dynarec. (Kammy in 3.41) i gave my thanks to Aerialx for this and regarding other devs you can see with your own eyes (robo hobo and others) you know that when you null the NX protection BIT in LV2 was a great advance never done in superiors FW to 3.50 and now itís possible in MA.
Thatís why the devs left aside develpoments when users passed to 3.5x.
In MA we get again this system giving us more power and possibilities to port more powerful emulators like = N64,dreamcast,NDS, etc.
As you can see in Emulator configuration we left the option *INTERPRETER* off in order to use Dynarec. As you may remember in 3.55 only you can run it but slow with interpreter mode on and bios hle bios emulated. Now any bios can be used with Dynamic recompiler.
I have to say that this new system will have Thegrid as a dynamic patch. Because of this you donít have to execute anything. Only the Emu.
TheGrid will come with SP1.3 integrated (soon to be published).
Now some other news, i have to anounce that me (Blackdeath)
I am making progress with a job regarding PS3SX which i updated using the source of Anonymous when he published in 2011 fixing some new bugs and optimizing Dynarec.
If i have time enough i will improve it as N64, the only thing left to say to all the devs that we do what we like most that you are invited if you want to join contributing with this development platform that is 3.56MA.
As you know in PS3SX some shaders and filter are missing and for the moment we are at full speed using PE OPS (software) if we had the hardware plugin to obtain better quality like HD mode in 360 will be awesome to have that with the help of other devs that will like to help me to port this to PS3.
A pleasure, Blackdeath.
Pretty cool stuff, if you ask me.
