I posted it in the PS area where it belongs. I have spent a good part of this weekend with PS again. Maybe it would be best if you didn't update it. I might quit my job so I can play with it all day :) If it's not open source, have you considered making it so? This would take pressure off you maybe a bit. Thanks! Mike (again) I was able to post what I intended to post the other day but could not for some reason. I posted it in the PS area where it belongs.

Both pocketSand and the game will be put on hold, with all my dislike, but i'll need to concentrate on the new work. Thank you for your support Mike, really appreciated! Ahah, you are so right Mike ;)

(hehe) I laughed out loud when I read the comment. All that typing about integer math and the comment is back on Pocket Sand. This should tell you that you have a winner app here. Your article brings back fond memories of the days when optimization for speed was paramount. I remember when it hit me that I didn't need FPM in an application I wrote, that all I needed to do was multiply * 100 and I had 2 "decimal points" in an integer. Yes, it limited the maximum value, but I think that app was only managing a value between 0-100 (percentage). The speed improvement (this was on an 8086 or maybe a 286, but I think 8086/88) was huge! I wasn't doing any fancy stuff like you're doing, radix/mantisa/big shuffling is more complicated than I ever needed. But yes, a FPM emulator library for Pocket PC would probably be of interest to the community. Good luck! ...now, when are you going to get back to Pocket Sand? (^_^) Pocket Sand is really great!

Obviously i could post some screen shots, but they are just work-in-progress stuff: i plan to say more on that game whenever we'll work out some more details.

Are you allowed to tell me what the new game is?

Thank you for the interest btw! Hi terik,
