Check our previous releases in the News Forums and of course the many sections linked above. Last year for our 23rd anniversary we released Not-for-sale "Game de Check! Koutsuu Anzen" from complete with a full English translation. Today we have 5 prototypes to share! If we forgive the comparison to its predecessor, Zillion II is actually quite a fine game which lends itself to quick replays.
The fast-paced shooting sequences sometimes may almost feel like a rhythm game, and the on-foot sequence have their share of exploration. The most visible difference in this version is the earlier title screen: Left: prototype, Right: retail version Actual game appears to be mostly the same, can you find any difference?
This basketball game developed by Aicom is best known for its highly detailed shots of performing a dunk: This prototype version appears nearly complete.
Among other things, we noticed that the Credits Sequences bears a different title for the programming role: Left: prototype, Right: retail Our third release is A prototype of Rastan for the Master System. This appears to be a much earlier build than we typically find prototypes of. Among other things, this build of Rastan - is missing title screens - has different enemies and palette e.
See more screenshots for Rastan. Our fourth release is A prototype of Taito Chase H. Competitions Entries are being posted in the Competitions Forum , with a few more expected later today. We will start voting on entries from tomorrow. A peak at some of the entries Check the forums for more! Comments 8. Reminder: we are holding the yearly coding, music, hacking competition to celebrate SMS Power! After more years of research and collecting of bootleg titles I was able to uncover a lots more.
For those not acquainted with the hardware, the Game Gear is hardware compatible with the Master System and therefore those games are "regular" Master System roms. Plenty of bootlegs were released in Asia in the nineties, often in the form of compilation X-in-1 cartridges. The Hung Tao Hsin releases from Taiwan are notable as they were single title, with box and manual, frequently borrowing quality art from Japanese releases. Below we will be listing games by including the english name on the box, the chinese or japanese name on the box, and the name of the actual title contained within.
Another thing HTH did with their release is that they commonly made the games easier by patching the number of lives initially available.
See: So those dumps are essentially Taiwanese hacks from the nineties. Thanks to Billy Lin for proofreading the Chinese inputs. Comments 4. As with every year, we are running a fun Sega 8-bit Coding, Music and Hacking competition. Deadline is March 27th, Most included both the ability to both apply cheats and to search for cheats.
Similar to the other cartridge-based systems, the X-Terminator fits into the cartridge slot, and the game cartridge connects into the X-Terminator.
It shows a menu on startup to let you enter cheats before starting the game, and the ability to return to this menu in order to search for cheats, resetting the game each time. You can also adapt Pro Action Replay codes which are much more well-known. Let us know if you find any cool cheats, and if any other emulators add support for this!
The console - essentially our Sega Master System - was released on October 20th, The working title for Bomber Raid was Battle Wings. In fact, the retail version of Bomber Raid contains a hidden cheat to activate the old title screen. Among other things, this version of the game lacks the Bomber Raid title screen, lacks the introduction animation and has amusing typos in the text. This early prototype with a "" date on the title screen vs "" for final version notably includes a rendition of Passing Breeze which is absent in the final version.
If you compare Out Run 3-D screenshots and Out Run screenshots you'll also notice the Start section in this prototype is closer to the one in Out Run, as presumably Out Run 3-D was programmed as a derivation of Out Run and slowly evolved into its final form. Cyborg Hunter Prototype for the Master System. Whereas the final version refers to the hero as "Paladin" and the enemy "Voltron", this prototype refers to them respectively as While the latter name is common enough, I wonder if it could be the name of a Sega employee involved in the localization?
View all news items - News RSS. Login Report an error Print. Cliffhanger Intro 6. Happy holidays! We have three new prototypes for release today! A prototype of Streets of Rage II for the Game Gear This appears to be a fairly late prototype as Greenalink reviwed it and couldn't find many differences.
A word from them: Quote: Hello readers, As a die-hard fan who played the game to not only 1 Credit Clear the game on Hard but also speedran it at European Speedrunner Assembly charity events a few years ago, I was really interested to see if I can spot anything different.
First, I had a look and checked if the cheats still work. From my playthrough as Axel, I didn't noticed anything different. The SoR2 GG quirks from final build are still in the prototype build including stamina differences Skate dying to an explosion and always facing left when walking upwards.
The only mode I couldn't test properly is multiplayer due to the lack of a good Game Gear emulator from my knowledge and lacking 2 Everdrive carts to test it on real hardware. Use the arrow keys to select, and press start to choose.
The rom should load, and you should be playing. You can load a rom without audio which will improve frame rate, but you won't get any sound obviously. Once a game is loaded without audio, the only way to get audio back is to reload the game. Some games will freeze with audio disabled, so be warned! This will improve the speed of some games, but is never required. The main gui screen will display the text SLOT2 if this feature is active.
Normal is a cropped screen. Scaled shows the full screen, but scaled down to fit. This can actually make some games run faster! It is easier for NeoDS to emulate a slower cpu, and some NeoGeo games don't use the full cpu power anyway. Experiment and see. Touch anywhere to turn it back on. DS buttons are down the right side of the screen. NeoGeo buttons are along the top of the screen. Each row of boxes coorisponds to one DS button. Putting a check in a box maps a NeoGeo button to a DS button.
You can map multiple NeoGeo buttons to a single DS button this way. This can be useful for fighting games, or for other things. Please report any crashes to me. The more info you can give me, the better. In this case, it takes up to 2 parameters. In this case, only this rom will be converted. For example, pretend you want to convert Metal Slug 1, using the japan-s2 bios. Copy mslug. To open a command line, click start, select "run Press enter. Then type "NeoDSConvert -bios6 mslug".
If you want to use the universal bios, name the file uni-bios. This enables lots of nice features like switching between home and arcade mode, and cheats. This is the recommended way to use NeoDS. Graphics, sound, and program code all need to be streamed into ram constantly while the emulator is running. NeoDs uses a modified libfat which has a lookup table to vastly speed up seek times.
In the future, slot2 ds ram expansion packs could provide some speed up. But they only have 32MB, so games will still have to stream. The emulator uses a slightly modified version of Cyclone for the m68k core. The memory handlers are all done in assembly code and integrated into the core. The jump table is also compressed using a series of sub jump tables. This uses an extra arm instruction to decode each opcode, but reduces the.
This seems to give a slight speed increase. My feeling is that cpu emulation is heavily memory bound. I think a smaller m68k core that fit mostly into the TCM could be much faster than cyclone, even if it needed more instructions to execute each opcode. The NeoGeo sprite graphics are all done with textured quads using the ds 3d hardware. The NeoGeo tile layer is done with a ds tile background.
