Well, I downloaded a NEMESIS Clone GR 3 Project from a japanese web page and I have unzipped it now, but... I don´t know how to make run in my PC.
I´m not sure if it´s a game for an emulator, real MSX or PC. What should I do? Copy it in a floppy to play in a MSX? Could anyone help me. I´m dying for this game! It looks very good!
Please help me soon!

The game is written in JAVA, so you have to play it on your PC, but you need to have the appropriate version of JAVA installed.

Ok, I´ll tell you from the beginning:
I downloaded JAVA WEB START version 1.4.2_03 (Build b02) from SUN MICROSYSTEMS WEB. Is it the correct one or not. If not, tell me which one is the correct for playing the game, please. (Yes, the GR3 Project web talks about something related with JAVA but everything is in japanese)
1.- I went to the web page http://naramura.kdn.ne.jp/msx3/g3project/ and I clicked on the GR3 picture. The game was downloaded then (I think so).
2.- I unzipped the file and inside I unzipped also the file called "Gura3 Class" with WinRar.
3.- Now inside gr3stand folder (game folder) I have a lot of files that I can´t deal with. Some of them are sprites and others are Stage, Ememies, etc. But I don´t find any executable file in it!
Could you tell me or anyone who reads this step by step how to run this freking game?
Also the web page is in freaking Japanase (no idea what to do) Anyone who can read Japanese?
Thanks dudes

look for any html page... java programs usually are loaded from them.
Or if a .JAR file is present, try (from command prompt) java filenamed.jar (change filenamed.jar with the name of the found file). if it fails, look yo the java help (executing java with no params)

Thanks to all
finally I did run the game. I was wrong first cause I downloaded not the game.
My biggest problem was that page in japanese but now everything is ok.
The game looks fine and many of the sounds and backgrounds are taken form the NEMESIS saga. Good game though...and freakin difficult!
C U dudes!
