I am going to start releasing single game dosbox packages. This is using an unreleased version of Dosbox from GPF. I am sure there is no saving for any game released. I am not sure that controller can be used. I dont have my Dreamcast currently hooked up so i dont know if any of the games run fullspeed or close to fullspeed but i do know that you can change the FPS with F11 and F12 if i am correct the same keys you use to change the FPS for the DOSbox on PC.
This also contains the source to Dosbox the latest release. I also have permission from GPF to release single game packages. The game i have here is a personal fav i used to play when i was a kid called Leaper its a clone to Frogger. Again i have no clue how fast this game is and again you can change the FPS with F11 or F12 if this will make the game near fullspeed.
Dont bother GPF about the updating the Dosbox for Dreamcast he has done all he can with it and i dont think there is much more that can be done.
BTW if this one doesnt work i know how to get it to work i have to play the game atleast once on the PC so it can make a cfg file i believe for Highscores again the Highscores cant be saved but it must be with the game in order to run so i hope this will not be an error for the Dreamcast.
To change FPS hold CTRL and press F11 to decrease and F12 to increase.
