say JR, you told several times you were a professional game developer. Can you give us a hint, which games you worked on?

If you don't get anything after you press start then there is something wrong with the system ROMs that you are using. If you do not select a game cartridge at all you should still be able to boot up the system with just the system ROMs installed and get to the BASIC prompt. Have you compressed the system ROMs or are you using uncompressed files? To play MG2 you need to have msx2.rom (size 32kB) and msx2ext.rom (size 16kB) -- or if you are using gzipped roms, msx2.rom.gz and msx2ext.rom.gz. These files must be in systemappsfmsx
om directory. |

I hope you aren't expecting something fancy  None of the titles are probably familiar to you -- finnish game companies are not as big or visible as the big players in the business... hmmm... one of the games you might know on PC is called "The Driver" - I did not program that but I coded a version of it for Palm OS - too bad Infogrames decided not to publish it after all...
Hmm... Okay, here's one you can still get from the web  I was one of the two main programmers of the snowboarding game (virtually board snowboarding) that we did for Nokia for their 9210 Communicator - the game is available from Nokia's software market.
I was also involved in PC stuff earlier but I guess you wouldn't know anything about those as they were only available in Finland, like a modem hosted turn based multiplayer war strategy game for DOS called Metallic Nations. Oh, something you might know, an adventure game for DOS called Alien Incident - I was not really participating that project but I made a quick & dirty CD copy protection for it |

New Goboy version! This time is the 1.4 and guess the new feature... Multiplayer support via IRda and Bluetooth! It looks like this guys think like us. Jr, you can take a look again to the source code of the new version, to get an idea of how it is implemented.
About the sound, it looks like they use their own audio driver for the emulator.
Uhmm... the URL... yep, it was this: www.wildpalm.co.uk/GoBoy7650.html |

Maybe the GoBoy developers are reading this forum, hehe  |

Yes I know it has bugs, I'm sorry. I'm going to release v0.96 this week and hopefully fix at least some of the problems. |

I did some testing and found out that actually non-gzipped system ROMs were not working  So if you try with gzipped system ROMs the emulator should work. This is now fixed for the next release... |

Woah, I just got my 3650 back with updated firmware (software version 3.18) and I installed the version 0.95 of the emulator. I'm very impressed with the sound, it is much better than I though! I think that with some small optimizations it could sound enough well for playing without stoping screen refresh. The problems is... what optimizations?
Anyway, you are doing a great job Jr!
PD: At the spanish development forums that I wrote, nobody has written me x_x I wonder what can I do...

I'm glad to hear you are already happy with the sound support. I think you will be positively surprised with the speed improvements I have already reached for 0.96 even if they still are not enough (IMHO) for other than the "raw" display mode.
Also, the emulator can now be reset from the pause menu. I didn't realize how much it really improves the usability when you don't have to exit and restart the whole program to switch game...

Oh, I just tried the new Goboy with sound support. Oh man, it is so crappy, goboy's sound is so worse than fmsx's one. I have heard of another Gameboy emulator (not Gameboy Color) for Series 60, that people says that have good sound. It is called "Gamephone". I'll take a look at this...

About the two player support via BT:
The way multiplayer games usually work is that the game engine is separated from the user interface of the game. Only one instance of the game engine is running and the inputs of all players are transmitted to the engine which then processes the data and decides what happens next. The new state of the game is then transmitted back to all players' UI's to be shown to the players. This doesn't mean a screen dump but some sort of state information about the game world.
In a scenario where you have two players playing with eachother over bluetooth, infrared or whatever, one of the two devices is running the game engine plus one player UI and the other device is only running the player UI for the other player. So one of the devices is a "master" and the other is a "slave".
In the case of an emulator this becomes a bit more difficult if not impossible, because the emulator does not understand the logic of the program that is being run in the emulated machine. So the game engine cannot be separated from the UI. Okay, it would still be possible to send player inputs from one device to another and just let both emulators process the information but the problem is that it is not possible to sync the devices so well that the emulation would be running exactly in the same phase (BT/IrDA latency...) and/or some things like RTC clock can be different, unexpected background processes may take some CPU time etc. which means that you will end up with a different game state in the two devices (i.e. playing Salamander in co-op mode you would actually be running TWO Salamanders -- really two different games that would look more and more different the longer you would be playing).
To avoid the game engine problem in the emulator situation the other device would really have to be a dummy that only shows the MSX screen and reads & transmits user input to the other device. I think this is not doable, though, because it would require a lot of bandwidth to transmit the screen (for MSX, something like 3.5MB/s). Okay, maybe we could lower it down a bit by using interlacing or something else but still... I don't know. But I might try some day when I feel like experimenting more with this.
Of course, your views and suggestions are welcome, as always, and I will gladly discuss this further

BT fmsx is not important? because The MSX is Personal Computer for One Palyer or user. 2 player games I'm not see  But Mame, Nes or Sega Emulator needed BlueTooth...
Jr Do you think WHY eMAME Not Ported for Series60 platform??? eMAME exists on 9210, but not on 7650/3650 WHY?? It's terrible! |

C´mon guys, multiplayer via bluetooth is a *very secondary* thing. As Jr said, it is very very dificult to implement, and there are other parts of the emu that should be optimized... Let's leave him working on his way ^^
