Some nice developments in Dreamcast emulation scene today, with a major update to Reicast core.
With a new addition that now allows texture dumping, and injecting.
Dump textures: will dump all textures used by the current game to /dc/texdump/
Load textures: loads custom textures from /dc/textures/ to replace the ones used by the game
So now you havn't got excuse not to have a go at doing a HD Shemue!
Remember to check out and post your packs, or just to discuss on our Texture pack forums
more bugfixes:
- better G2 DMA edge cases handling
- brake in Atomiswave racing games works again
- fix crash in ROM-based SystemSP games
- weird AICA LSA/LEA handling tweaks
The dcemul team have been busy, and are now releasing alpha wip builds to see what progress they've made, these arn't full releases so take them as is:
by many requests we decide to make public build of emulator to show and share current stage of its development.
its an alpha/preview quality product so take it AS IS.
it includes new features and new systems mentioned in this topic, many bugs fixed, as well as several unfinished parts, like new DX11NG render.
enjoy.
- somewhat fixed save/load state for DX11NG
- adjusted sound volume, was too loud, notable in Atomiswave games
For those who know me know ive been a fan of emulation for 20 years or more, the reason i started a videogames website was purely because i like to play emulators of old consoles on a single device.
Recently the homebrew/emulation scene has been stagnant, no real breakthroughs means that the best way is to buy a device that is made for emulation fans like myself, i reviewed the JXD S7300 Android Tablet and for a fan like me i loved it. The Android tablet was for me perfect, the mixing of old style controls and touchscreen inside an Android OS and with Gamecenter X you could download games onto your console with no messing around, the console/tablet game with Android/N64/Megadrive/Arcade/GBA and Nes Emulators with games built in, beyond awesome.
But JXD since then have brought out a new and improved JXD S7800b Gaming Tablet which features PS1, MAME, Dreamcast, N64, NeoGeo, Atari, NES, SNES, Gameboy, Gameboy Colour, Gameboy Advance, SEGA Master System, SEGA Mega Drive, CPS1, CPS2, Amiga, Commodore 64, ZX Spectrum Emulation to name just a few, am i salivating ?, hell yes.
The JXD S7800b Gaming Tablet has a 7" 1280x800 IPS 5 Point Multi-Touch Capacitive Screen, RockChip RK3188 QuadCore 1.8GHz CPU - 2GB DDR3 RAM - 8GB Memory, Network Wi-Fi(802.11 b/g/n), External Ethernet，3G with Dongle and runs Android 4.2.2 Jellybean OS.
So this Android Tablet runs one of the latest versions of the Android OS plus comes built in with all them emulators and you can do what you would expect from a normal Android Tablet.
Tonight Emulation-X has posted an interview with the two coders behing the Dreamcast Emulator for Windows and Android. Reicast is an emulator coded by well known emulation coders drk||Raziel & Psyman.
Want to know more about one of the best and most active Dreamcast Emulators of the moment then check out the interview here.

As of, well, today, the alpha version of Sega Dreamcast emulator Reicast is available for Android. It's essentially an Android-based version of Nulldce.
Quick warning: the developer of Reicast reckons that you'll need to have at least a Cortex-A9 dual-core 1GHz+ processor in your Android device to run Reicast properly.
Given this is an alpha version of Reicast, you might obviously come across a few bugs. Otherwise, you should have no problem running the likes of Sonic Adventure, Crazy Taxi, Soul Calibur, Resident Evil Code: Veronica, and more.
Reicast even works on the Ouya, by the way. So, if you have one to hand, you download the .apk file and get it running on a big screen.
You can download Reicast for free on Google Play [Download here] right now.

A new test version of the Dreamcast emulator Makaron (NAOMI version) has been released.
Quote:
NAOMI Test 12/7. I don´t have time to work on T13 lately and I´m not going to rush it, so you get this instead. I experimented a lot on this code - it might be actually less stable than the previous version. On the bright side, Power Stone is playable now. Should be, anyway

• Support for real joysticks and gamepads (linux host only)
• Various bug fixes
Other Changes:
• Change timer (TMU) interrupts to be precise (within the bounds of a code block anyway)
• Implement SLEEP op properly in translator
• Clamp run speed in the GUI if it’s running too fast
• Run event loop more frequently to avoid missing keyboard events
• x86-64 architecture support
• Preliminary Mac OS X support

-PowerVR AA mode now works properly (omikron half screen problems, possibly others)
-Version changed to 1.0.0 beta 1.6
-nullExtDev no longer requires winpcap when not emulating anything :)
A NetPlay add on for nullDC, a Dreamcast emulator for Windows has been released.
Be aware that the NetPlay code is in early stages at the moment so it might not work as intended. Take some time to consult the included help file before attempting to use it.
fox68k has released a new version of the NeoGeo emulator for the Dreamcast:
This new version features the lastest FAME core and the new FAZE (Z80 emulator for DC). Basically, the emulation speed in some games have been improved, specially in Metal Slug 2 (i recommend to overclock the m68k and underclock the z80 for this game), Art of Fighting 2 and Pulstar among others.
News from Chui of a new release of Mame the Arcade emulator for the Dreamcast.
- Fast FAZE Z80 core for all systems.
- Lastest FAME M68K core.
- Q-Sound for CPS1 games supported.
- ArcadeSticks bug fixed (L+Start for exit).
- Rest of fixes and new features of MAMEGP2X incluyed.
nullDC has some quite impressive progress these days. After the recent changes and additions more games start to become playable. CDDA support was implemented so games with audio tracks now have music. nullDC also run Virtua Cop 2, its first Windows CE game (Tomb Raider Chronicles was booting before, but it wasn't playable). Some sound and GD-ROM changes also made Bangai-O playable.
Here are some screenshots of Bangai-O, Half Life and Virtua Cop running in the latest (unreleased) nullDC BETA. Click on the links to see the images.
DEmul is a Dreamcast emulator for Windows. It is developed by Wind, ajax16384 and CaH4e3. Even though this is the first release of DEmul, it already supports running commercial software (games) and has various features such as save states.
Here's the list of the features taken from the help file that comes with DEmul:
• No open-source for this time, sorry...
• Plugin system for GPU and peripherals (SDK and docs will be available later)
• SH4 Dynarec (fast and furious) and Interpreter (more accurate and compatible) modes
• MMU support (for Interpreter mode), Exceptions and Interrupts emulation
• Sound support (still imperfect)
• Four input ports up to 5 devices each
• DC Keyboard support
• Standard/VGA video modes
• TPU speed adjusting
• VMS manager
• Savestate support up to 10 slots (about 2-15Mb in size each)
• Original BIOS and Flash files needed (not included in release)
-- Credits to Exophase for releasing such a fine emulator that I have merely ported it to run on the dreamcast using the included C core, does not use dynarec like the psp version.
please check the other readmes.
included is a scrambled binary, game_config.txt. requires a gba bios named gba_bios.bin(you can dump it yourself, see http://wiki.pocketheaven.com/GBA_BIOS)
place your gba roms on the root of the cd and burn everything to cdr, in what ever method you need to make a bootable cd.
Warmtoe and BlackAura have been working on the update to the Genesis emulator for the Dreamcast and it now has VMU Support and is also very near Full Speed on most games.
