Reesy updated his page with WIP news the past two days. DrSMS is a Master System emulator for the Gameboy Advance.

9th April 2003 – DrSMS NewsI’ve put in code to emulate the SMS noise channel. I am only emulating noise modes 0,1 and 2 at the moment. Number 3 uses the frequncy on tone channel 2 as its input. I’ll need to build a table to translate these frequency’s. I have also put in the menu.8th April 2003 – DrSMS NewsMajor break through today, I have finally got the rasta effects to work. So you will be able to play games like Hang-on and Battle Outrun. I’m not however going to release a new version yet, I’m going to be really nasty and make you wait!. I still have to put in a menu system on some sort and I still have to do the noise channel. I’ve also had reports that the reset function does not work correctly. So instead of releasing another version full of bugs, I’m going to try and tie up a few loose ends before the next release. I may even put in some code to emulate the SMS pause button.
