Emulyator Sega Dreamcast Dlya Psp

This post is part of the series The news run fast, newbies begin to become excited and spread the happy tale: Sony PlayStation Portable is able to emulate the Sega Dreamcast! And the credit of this epochal event would go to the author of, an emulator that can already reproduce, with remarkable fidelity, the Japanese console on Wintel PCs. Obviously reality is very different, pretty unlikely nullDC will emulate Dreamcast on PSP and his author has ragged a great deal of gullible unable to reckon a bit before exalting themselves for nothing.

Jun 4, 2018 - Lakka is an all-in-one emulator powered by the RetroArch operating system. Of video game consoles manufactured by Nintendo, Sony, and SEGA. You can play PSP, PS1, Nintendo DS, Dreamcast, and even Virtual Boy.

NullDC has actually been converted to run on PSP and, while as of today binaries and source code of the software aren’t available, the author drkIIRaziel has put on-line on YouTube rather eloquent. The software runs on the little Sony console, but as to “emulate” the Dreamcast in the exact meaning of the word, visible evidences in the videos leave really a little doubt on the impossibility that the newbies’ “dream” will become real. Whether it lets run the internal BIOS interface or a game, nullDC in PSP version runs at 1 fixed fps. Surely, the emulator is capable of rendering 3D graphics (almost) like the PC counterpart, but numbers are numbers: Sega Dreamcast is a sixth generation console (the same to be clear of Nintendo GameCube, Microsoft Xbox and Sony PlayStation 2) with an SH-4 RISC heart working at 200 MHz able to produce a raw power of 360 MIPS and 1,4 Giga FLOPS, a PowerVR GPU of 5 millions of polygons per second, sound coprocessors, 16+8+2 Megabytes of RAM and so on.

In comparison, Sony portable console has a MIPS32 R4000 CPU clockable from 1 to 333 MHz (blocked to work at 222 MHz by official firmware until version 3.50), a GPU at 166 MHz and 32 (64 in the “Slim&Lite” version of the console) +4 Megabytes of RAM. A remarkable equipment, especially if compared to the standard of a console, Dreamcast, which was considered as the maximum power available at the beginning of the new millennium. But it’s an equipment hugely insufficient in respect of the task of emulating the Sega console. As clearly demonstrated by the videos put forth by drkIIRaziel, everything nullDC will ever be able to do in its PSP version will be to demonstrate that it’s possible to boot up the emulator, enjoy a show in slow motion and nothing more. The author himself had however already explained which was with the development of the conversion, namely the reengineering of nullDC code so as to make it independent from the traditional framework of Windows OSes and x86 class processors, to make the porting on the embedded systems and to release the source code at last.

From here to “emulate” the Sega Dreamcast on PSP, there’s plenty of way. DrkIIRaziel says that he “ manage to get playable speeds” of the software on the portable console, but considering that to make games under nullDC run at best on PC is advised a 2 GHz processor and a sixth generation GeForce, more than a concrete aim this seems to be a desire or, exactly, a style and programming exercise.

Whatever it is nullDC on the PSP once again demonstrates the vitality of the homebrew development scene on the Sony console, which especially on the front of emulation offers ranging from NES to home computers, passing through arcades and of course the PlayStation 1 emulator developed directly by Sony. Regarding Dreamcast, maybe it’s the case to remember that a console (particularly if it’s portable as the PSP) can’t be updated like a PC: power doesn’t increase, RAM neither, and in this context nullDC will continue to be only a style and code skills exercise.
