This is the offical build it uses stef d's c68k m68k emulator this core is the best and fastest at this time. From the test builds people complained of "to much speed", "missing frames of anmation" and the *shadows* and some missing grafix this is now fixed. Loading screens are messed on a few games but in game should be correct for the first time correct speed. Yes slow down on metal slug 1 and 2 is there. This is slower then the test builds as they were 120% speed. Smooth ness now should make up for this. You will noticed this on Rangnagard and most fighting games the new smoothness and flashing shadows fully working. Aero fighters 2 the planes now flash and grafix are correct. Z80 is running but sound is disabled let me know if any other games work with cdda music.

Thanks to fosters for the control fix and to quzar for all his great coding work on this emu.. This is a My Editon I use I thought I'd share.. Enjoy

NeoCD/SDL DC Version 6

Frameskipping: it was implemented before but not properly. it is fixed and set at ~4. Frame Limiting: This allows for the emulator to slow down if it is rendering too fast. VMU Display: Existed before but was broken, now displays a neo geo logo, saving... or "PUSH UP FOR REGION SELECT" when appropriate. Optional Region Select: Region select is now not default. To access it, hold up while the emu is loading. (defaults to USA) Game Autoloading: Now the emulator auto-loads game, no need to wait and hit start, just put in a CD when prompted, and the emulator will do the rest. Speedup: The emulator has been sped up by around 10% max, without the frameskip. When frameskip is taken into account, it runs almost completely full speed. Misc bugfixes and code optimizations. 2 players is via using 2nd player on the keyboard at this time.

NeoCD/SDL DC Version 5.5

Includes all updates given below. New in 5.5 slight speed up.. Tells you when the bios is loaded.simple stuff to help newbie's.

NeoCD/SDL DC Quzar-CL- Version 5 Metal Slug edition!
New in V5 this version has a region selector so you can chose what region. Also i have made it so a saving txt will display so you know when it's saving.. Now there might be a problem saving with the vmu from changed regions. Screen and display should be flicker free and speed should be slighty better on all games and less slow-down. Less memory is being used again so other games may-work. Quzar did the selector me and him sat on msn all night going through it.. SO it's like the quzar editon..

This new editon is the start of a new way of doing this emulator. This version is like it's own mini dream inducer, very basic mind you. New graphics, and music for Christmas. You can swap rom cds making it alot easier to burn. Look at wowpack A and C lists to get what games are available for those paks. WowPack B supports 700 romsets. More info in the readme included.

This is the source to the unofficial update that was put out a couple years ago.

"[A2600/A7800] Fixed reset handling. [Nate Woods], [A7800] Fixed RAM0 and RAM1 bank handling, which has been broken since MESS 0.61. Ikari Warriors now runs, among other games most likely. [Nate Woods]." These changes and more are now ported to the new DC7800 mess build sound is improved. Speed does vary across the range of games some run very well other dont.

One of the only Spectrum 128k emulators for Dreamcast. Play most of the games you used to on your DC. Some games may not work due to timing issues. I would like to make a list of working/non-working games please post it so I can include it here. You MUST have a keyboard to use this emulator.

Tatio Coin-op hits pack of taito games including are New zealand story, Arkaniod2 ,Extermination, Insector X , Kageki, Chuka Taisen, Dr. Toppels Adventure, Plump pop. Credit to the mame PC team and ice88.

Based off the ported m.e.s.s. by ice88, is the Vectrex emulator. LIGHT PEN and 3D IMAGER games are not compatible.

Pacman Pack- All are running at 100% speed with NO frameskip. Pac-Man, Jump Shot, Lizard Wizard, Magic Brush, Make Trax (set 1), Mr. TNT, Ms. Pac Man Attacks, Ms. Pac-Man, Puckman, etc.

This is a new build that has all of the improvements by the mess team and ice88. The new file selection code lets you load roms from the main GUI. Graphics by Gabbi.

Simpsons/Vendetta Pack- These games are running between 70-100% speed. With what I can do, it's as good as it gets. This is not an SGA (single game arcade) release.

This is based off Ice88/Warmtoes work on M.E.S.S. and M.A.M.E. source code 0.71. It's running at about 36fps, which is a great speed for lynx. The only gam tested is rygar, so other game speeds may vary.

From the source of the original release I managed to code in fullscreen support. I will be working on this in the coming months to see if I can get sound as well. Keep checking back for news and info.

My first emulator port. Although its just Space Invaders, it taught me alot in how code works for certain things. I'll be looking at other sdl emulators in a while.
