SMSPlus "Project"

[eke-eke]

[INTRODUCTION]

This is a port of Charles MacDonald's SMS Plus emulator, based on Softdev's last release, with some compatibility fixes and additional features. Download the latest version and execute smplus.dol on your Gamecube or Wii with your prefered method and then load a rom from ISO9660 DVD or from SDCARD. If you use SDCARD, roms must be placed in the previously created directory /smsplus/roms. Savestates need a /smplus/saves/ directory.

A complet user guide can be found here.

KNOWN ISSUE: expansion controllers (Nunchuk or Classic) are sometime not detected upon initialization. To solve that, simply deconnect and reconnect it from the wiimote.

Thanks Eke-Eke that's great work.

Any chance of sub directory SD support when you have a spare moment?

Thanks

Chris

[eke-eke]

Sorry but I have no idea how to detect/read subdirectories with sdcard lib...

I even don't know if it's actually possible

[chrisino]

Hi Eke-Eke. JLF65 sent me a compiled version of amendments he made to the Genesis and SNES emulators with sub directory support from SD card.

Hopefully JLD65 won't mind me sharing this info to find how to do the same on SMSPlus.

If I email it to you could you have a look to see how it was done?

Thanks

Chris

[nufather]

What else is there to say?

AWESOME JOB GUYS!!!

thx,

sure, you can also upload the modified sourcecode in genesis plus thread so that everyone could take benefits from these amendments

I was about to do that.

Nice work! I need a little help for testing it though, could anyone tell me what file do i need to modify for the "smsrom.s" to work again? I use the BBA+PSO setup, and injecting a ROM in the source is my only chance for testing, for the time being, since this emu doesn't use an 'inject.exe' kind of method (until i can get a hold of the SD adaptor).

you can find the old version with smsrom.s here: http://www.tehskeen.com/forums/showthread.php?t=4104

[eke-eke]

Following genesis plus, here is the latest smsplus release, with SDCARD subdirectories browsing and LFN (max 255 char.) support...

It has been compiled with last libogc (04/02/07), don't try to compile the source with previous versions of libogc, it will not work.

Download from the first post

[chrisino]

Hi,

I don't know how to compile. Could someone post the dol file of the new compiled version.

Many Thanks

Chris

I know it's a lot of efforts but check the files attached in the first post of this thread, they have been updated

[chrisino]

Sorry Eke-Eke. I didnt realise the binary version was a dol file.

Apologies.

Chris

Yup, i already had it, what i want to know is if it's possible to "activate" it again adding a line of code in another file on the current source. Thx.

[eke-eke]

ok, it's easy...

in ngc.c, you have to:

- change the following declarations

int smsromsize;
uint8 *smsrom;

to

extern int smsromsize;
extern uint8 *smsrom;

- in init_machine(), remove this:

/*** Allocate cart_rom here ***/
smsrom = malloc(1048576 + 32);

if ( (u32)smsrom & 0x1f )
smsrom += 32 - ( (u32)smsrom & 0x1f );

memset(smsrom, 0, 1048576);
smsromsize = 0;

- put your "smsrom.s" file in ngc directory again

Thanks man!! I'll try this right now.

[eke-eke]

Here is a small update for smsplus, only with minor additions to fit genplus last releases (see genplus thread for detailled modifications)

(26/03/2007):
- use ASM GU functions used intead of 'C' ones for rendering speedup
- added DVD automount
- added "DVD motor off" feature
- corrected Memory Card mounting function

Download updated source & binary from the first post on this thread

[eke-eke]

I managed to solved the problem of Master System games not being "fullscreen" displayed (on some games, it seemed that the screen width was shortened)

The problem was in "video_update" function, when updating vwidth & vheight variables regarding actual display mode: in fact, some games use an extended display mode which increments the active display size to 224 or 240 lines (192 lines by default)
What we previously did was testing if this extended mode has been set and, if it was, setting the display WIDTH to 224 pixels (256 by default). This was not correct, we have to change the display HEIGHT, not the width

I corrected this and also corrected the way the bitmap offset was calculated (always 0 for sms games, precalculated value for gg games for little speedup) and now every games are correctly displayed

I also modified the audio mixing so that FM music is correctly played (only PSG should be stereo): try Wonderboy III with FM enabled and listen

Hope you'll enjoy this...

As usual, updated source & binary can be downloaded from the first post on this thread

Finally, i tested the changes thoroughly, but, although it compiles well and it boots in the console, the moment i press A to get pass the agreement, it shows an error for a brief second and then resets the console. Is it something i'm missing, eke-eke?

I'm using the latest version of libogc (libogc-src-20070204.tar.bz2).

[eke-eke]

Hum, effectively, I was missing something...

in smsload.c, replace

extern uint8 *smsrom

with

extern char smsrom[];

I tested myself & it works now

[marzsyndrome]

Is there a chance a banner could be made for this program, or at least a logo I can use to base a ppm on in Paint Shop Pro etc? I'm trying to give each emulator their own unique boot banner y'see.

[reakt]

first of all, thanks for all your work on this awesome tool!

i am getting a black bar across the top of the screen on my PAL system. is there any chance of an updated dol like the genplus-PAL50.dol? it works perfectly for me. thanks in advance!

could you please test the attached dol and tell me if the "black bar" problem is still there ?

thanks

the black bar is gone, but i can't get any roms to load. thanks again eke eke

[eke-eke]

huh ?
i didn't change anything in rom loading , what is exactly your issue ?



Regarding the black bar that is gone, it's good news. I simply forced the mode to TVNTSCIntDf (60hz, 480 lines interlaced, antialiased) regardless of the detected TV mode.
If this is confirmed to work both on PAL Gamecube and Wii , updated version of the other emulators should come soon

[reakt]

huh ?

well i am using the multi loader, i select SMS and it shows up the title page fine, no black bar. then i select load rom, load any of my roms, then try to play game and it simply displays a blank screen. i can use the z button to return to the menu, but no matter which rom i load, all it will display is a blank screen.

the roms i'm using are zipped, but they work fine with the older version of the emulator (apart from the black line of course )

[eke-eke]

Hmm, if you say that only the menus are ok, it could be a problem with the GX (which is only used during gameplay)
Perhaps it doesn't like the NTSC mode we are using, I don't know

It would hugely helpful if you would download and try Snes9xGx 2.0.1b6 and see if you have the same problem. I'm using the same technique there as eke-eke was using here. If you get the same problem then we know it doesn't work. You can get Snes9xGx 2.0.1b6 in message 1 of that thread.

i have just tried out Snes9xGx 2.0.1b6 and I'm happy to say that it appears to work perfectly. I don't recall ever having a "black bar" problem with any version of Snes9xGx though.

i was previously using Snes9xGX 2.0 denman's special version (PAL50), though as stated, NTSC games were running too slow. they now seem to either be running the normal speed again or maybe slightly fast. i'm not exactly sure as it has been years since i played these games and i don't have an actual SNES to compare with. anyway, slightly fast is better than too slow if that's the case.

also, in regards to SMSPlus, not sure if this helps or not, but i was having the same "black bar" prob with GenesisPlus until i downloaded this version (PAL50), which works perfectly.

well, thanks for all the hard work guys!

[eke-eke]

yes, we know where this "black bar" problem came from, that's why I previously made a "PAL50" genesis plus version (if you try the other emulators, which haven't yet be fixed, you will have the same problem)

anyway, so it seems that the fix for pal is working and that we should always use the NTSC timings and not MPAL
the problem with smsplus must be something I introduced while testing
, I will have a look when I get my TV back
