SPI progress

I started from the part that was in the best shape, the first version of the tilemap layers, and fixed the decryption errors.

This encryption is used by Senkyu, E-Jan High School, Viper Phase 1 and Raiden Fighters. I will look at the other versions of the tile encryption next. Sprites are harder to do and will be done last.

Wow is that a hentai game? Also, what is encrypted besides the graphics? Is there anything else standing in the way of emulation?

You are the best!
There is no question about it.
Do you have any pics of Raiden Fighters or Viper Phase 1 with improved grapics or are you waiting to surprise everyone?
Thank you so much for fixing up these games Nicola and congrats.

Nicola is the best, but let's not forget Ville who started it all and achieved near perfect decryption of the tilemaps. Perhaps if he hadn't done it, Nicola wouldn't have had the motivation to start working on the SPI decryption.

what can i say ? that's simply incredible, you're a genious, a guru ..... ;) as other fans, i'm dying to see a raiden fighters picture .....;) .

I have a question, is tile map from raiden fighters different from raiden fighters 2K and raiden fighters Jets ?

Thanks a lot for your efforts, talents.... etc ... !!!

Yes that's true, Ville started it all and is a very impressive guy. But now Ville seems to be devoted on emulating Sega Model 3, and that's a very good news that Nicola work on this big piece of stuff !

To all Newbies i thinks it's important to remember :

From ->

"On December 24th, 1996, Nicola Salmoria began working on his single hardware emulators (for example Multi-Pac), which he merged into one program during January 1997. He named the accomplishment by the name of Multiple Arcade Machine Emulator, or MAME for short (pronounced as the word 'maim' in English, other languages may differ).
The first official release was MAME 0.1, which was released on the evening of February 5th, 1997 (23:32 +0100). Using a modular and portable driver oriented architecture with an open source philosophy, it soon grew into immense proportions. The current version supports 5428 ROM sets, 3020 unique games. Because MAME releases happen whenever they are ready, at one point the wait between new versions was almost 4 months. To help the agony of the users, a public beta system was used, with a beta release happening every 2-3 weeks on an average. However, now the beta designation has been removed in favor of a good old 0.xx version number. Also a work-in-progress -page exists, if you really want to know the latest information.

Even though MAME allows people to enjoy the long-lost arcade games and even some newer ones, the main purpose of the project is to document the hardware (and software) of the arcade games. There are already many dead arcade boards, whose function has been brought to life in MAME. Being able to play the games is just a nice side-effect. The huge success of MAME would not be possible without the talent of the programmers who joined to form the MAME team. At the moment, there are about 100 people on the team, but there is a large number of contributors outside the team too. Nicola Salmoria is still the coordinator of the project"

Thanks to Nicola Salmoria
