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.

More news about GP32 MAME

Hando over at GP32 X-Treme also had a look on ryleh’s latest piece of work which is a MAME port for the GP32 (unreleased yet). Hando offers a couple of other screenshots which GP32emu didn’t had.

As promised yesterday, some more info about M.A.M.E. for GP based on 0.66 sources. More than 20 games is supported, mostly Sega System 1. Emulation speed deppends on game. Actually all titles except Time Pilot (quite slow) are very playable. Emulator supports zipped roms, what is great feature if we consider that oeriginal MAME supports more than 3000 games. Of course GP32 wont handle even a half of them, but even than those supported games will took a lot of space. There is no chance fo public release because at current stage author is concentrating on emulator core, than he will start to add support for more games. As everyone knows, MAME sources are one big mess, so we have to be patient. A lot of works is still to do. But despite of this, Rlyeh has made a really great job so far.

gp32 MAME WIP (Arcarde emulator for GP32)

News taken from GP32emu:

Rlyeh sent me an alpha version of his MAME port, which supports about 9 drivers correctly for now, it supports more games of course but not all fully work (check the related discussion on the message board).Other games are in progress, but the palettes need to be fixed. The games that run for now seem to run great, with no emulation bugs (keep in mind it is a port, not a rewrite), even though speed isn’t 100% yet, andthere is no sound. The good news is, there is zipped rom support.Also, keep in mind this is his very first test version, and is only an alpha. Please do not bug the author, as this is just a test version, and not fully playable. This is just to inform you of the progress 🙂 Here are some screenshots of 1942, Pooyan, Burger Time, Solomans Key, Gunsmoke and finally Ghouls n Ghosts running on the GP32 taken through GeePee32, click on them for a larger image.

Tweakmode (GBA demo)

Guyfawkes recieved a new demo from MrMr[iCE] to publish on GBAemu. Binary and sourcecode are avaliable.

This is just a small demo of some techniques I picked up and a preview of a 3d engine I’m in the middle of writing. The screen is split in 3 sections. The top and bottom graphic areas is a mode 0 tile map while the middle is a”tweaked”mode 4. It is rotated on its side and scaled to fill the screen, but with only half the resolution of mode 4. This allows me 2″buffers”to draw in with only one page of vram. Page flips is accomplished by tweaking the BG x register to show the other buffer.

DrSMS v1.03 (Master System emulator for GBA)

New day… new version :o) But read more:

I’ve got DrSMS to work with pogoshell, I just need to write an exit function to return back to pogoshell. I’ve re-written the character data routine so a few more games work, I’ve also put in some code to check for 200 Byte SMS rom headers ( I had completely forgotten about these ) so a few more games should run. I have also made a change to the background scrolling routines, Because DrSMS is never going to run fast enough to get rasta effects working right I have stopped the emulator changing the xscroll value of the backgrounds before the SMS Vsync. This will allow you to play a load more games without them flickering. I will continue to work on a Vsync option that you can switch on and off, but with the Vsync option”ON”the speed of the emulator will drop drastically. Anyway after I have written my EXIT function I will release another version.
