FXPAK (SD2SNES) / Re: SD2SNES Pro
« on: February 10, 2019, 01:05 PM »
Short answer: No.
Long answer: Noooooooooooooooooo.

What is it with all the Gameboy on the SD2SNES requests?
I'm with ya on that one. Especially since we have a wonderful Gameboy flash cart from krikzz. Pair that with a super gameboy 2 and you're in a wonderful world of 8 bit hand held gaming on the big screen. I can understand where people are coming from to a point. It's convenient and easier on the wallet if the sd2snes does everything but people need to curve there expectations.

The only problem is the SGB2 is unusable unless you have a Japan SFC a lot of us only have the regular SGB which works on international SNES consoles. Also it's interesting to note the SGB2 rom actually loads on a stock SD2SNES but nothing responds on it so you cannot use that custom boarder anywhere... besides I prefer the stock SGB boarder even though I prefer to use custom SGB boarders that load up with any game.
Any japanese super nintendo cart will work fine in an american snes. There are 2 plastic tabs inside the snes cart slot only present on the american units in both the original and small redesign. If you cut off or snap those tabs off the japanese carts will fit and work fine. That is literally the only thing keeping japanese games from being played. I did it with a pare of needle nose pliers.
The super gameboy 2 works great on my american snes and gameboy carts are region free out of the box. They dont require any modification to work and will fit in both japanese or american super gameboys or hand helds. When it comes to pal or european snes carts they may fit like japanese titles but the difference with pal and ntsc signals will most likely result in no picture or a flashing image due to the different refresh rates. Just thought id add that too just to be thorough. So yes you have nothing to worry about if you wanna get a super gameboy 2 instead of the original since the 2 has the correct cpu clock speed.

FXPAK (SD2SNES) / Re: Modify SD2SNES PCB to fit NTSC cartridge shell?
« on: February 10, 2019, 10:45 AM »
I ordered a custom NTSC style shell and label from an etsy repro seller for my SD2SNES (rev. J purchased from krikzz.com came in their SFC style shell). I understand I'll have to dremel the new shell to make room for the extra contact pins and the USB & SD slots. When I did a dry fit for with the new shell I was surprised to see that the top corners of the PCB seem to run outside of the boundary of the NTSC shell.

Some photos of what I'm describing:

There don't appear to be any traces on these areas of the pcb. Would it be safe to cut down these spots to fit this case? Or did I get a repro case that's somehow different from a standard one that should fit easily?

Thanks.
Short answer? No. Someone who makes the thing would have to chime in to be 100 percent sure but many pcb's have hidden layers which you will damage by trying to cut part of it off. Your best bet is just buying a universal shell or an american shell for the sd2snes specifically or just cut the shell you have there but not the pcb. Better to do that than risk ruining a 200 dollar piece of tech my man.

Could the Sd2Snes Pro can emulate GBA as a Super Retro Advance Carteidge?
Maybe? 😜
the super retro advance cart is literally a clone gba system on a chip. the snes isnt even used for anything other than power and controller input. it doesn't even process or display the graphics of the cart. the cart has a 3.5m output for RCA audio and composite. I am pretty sure what you're wanting to do just isn't feasible.

Been saying for years now, would be cool to see more FMV ports of some kind, like Roadblaster.
That would be pretty awesome. I wonder if Dragon's lair could be done.

I think to put it layman's terms the fpga in the sd2snes just doesn't have the resources needed to emulate or I simulate an entire console
No, to put it in layman's terms, the SNES itself doesn't have anywhere near enough bandwidth to stream NES video.

So even if the SD2SNES could emulate an NES or whatever, some pretty crazy tricks would be needed to get around the fact that you have ten times less video bandwidth than you need, and more likely you would need a way to output video directly from the SD2SNES itself (cf. the Super Retro Advance's video output on the cartridge itself).
Right thanks for the clarification. Even if someone found a way to do it. It really doesn't sound all that practical to be honest.

A couple of years ago someone asked ikari_01 in a german forum if it would be possible to emulate the GameBoy or even the NES inside the SD2SNES FPGA - his answer was (sorry for my bad translation):

Quote
For the NES it's impossible or close to impossible. The Super Gameboy may be possible... but you would have to take a look, if the FPGA resources are enough for a Gameboy. The Super Gameboy doesn't just contain the Super Gameboy ROM, but a complete(!) Gameboy as well (well... without an LCD and without buttons ;) ). Still someone has to write the Gameboy in HDL.

The second challenge would be the video transfer. Since the system is 'emulated' inside the cart audio and video somehow need to get to the multi-out ;) . Audio isn't a problem at all since you can send it analogue via the cart slot. Video is a big problem, cause you need to send it digitally. Gameboy seems to be simple: the picture is relatively small and only has 4 colors.

Gameboy resolution: 160x144 pixel
color depth: 2 bits per pixel (4 grayscales)
amount of data per frame: (160*144)*(2/8) = 5760 Bytes
The SNES is able to stream around 6 kB data per DMA inside the vblank into the VRAM - so it's a tight fit.


But with the NES you'll reach the limits. While using some rasterisation tricks the picture can contain 64 colors simultaneously... and even more while using emphasis bits. Resolution is higher as well. Since you can only have 4, 16 or 256 colors on the SNES you'll have to use the 256 color mode.

NES resolution: 256x240 pixel
color depth: 8 bits per pixel
amount of data per frame: (256*240)*(8/8) = 61440 Bytes
As you can see: you would need 10 frames to send one NES frame - which doesn't make sense :) .


Without any conservative transmission techniques (prerendered frames, pixel by pixel) and with some smart HDMA tables you may be able to outsource some of the rendering work to the SNES PPU and only have to stream tile and palette data. Maybe a compromise between the CPU via S-CPU inside the SNES and PPU emulation via SD2SNES would be possible. But that's some kind of complexity i wouldn't wanna think about right now.
Thank you for this. It explains it much better than I ever could. I think to put it layman's terms the fpga in the sd2snes just doesn't have the resources needed to emulate or I simulate an entire console even if it's just an nes let alone a gameboy advance. The GBA may seem similar to an snes in visuals but the hardware in that sucker is pretty robust compared to the snes.

Hi everybody. I have a SD2SNES cartridge. It’s fun. It’s the ultimate cartridge for Snes. Thank you so much for this awesome product and it awesome firmware!!

I like also the GBA games. I play it on my GBA, my DS, my Gamecube and also with emulation on my raspberry.

Iwould want to play GBA games on SNES but the only one product os the super retro advance... it’s not the better product for image... and it’s impossible to have it.

So I ask me about the SD2SNES...

Do you think that this cartridge can play emulators (GB, GBC, GBA or other)
Do you think that a new Everdrive for SNES can be create to play these games on SNES?

Thanks a lot.

To put it simply no. There was talk of people wanting the SD2SNES to emulate the super gameboy but I really doubt the fpga on board is capable of doing it. As for gameboy color or gba? not a chance. I'm sure people alot more knowledgeable about the subject can explain why. The super retro advance is literally just a GBA clone system on a chip inside a cartridge. all it uses the snes for is controller input and power. The thing doesn't even use the snes to output video requiring it's own 3.5 mm jack to composite out cable for video out.

From what I understand first the snes is not powerful to emulate any system you mentioned not by any chance at all. If you made a cart that did it using an FPGA like the many FPGA clone consoles we have now like the analogue nt mini or super nt the snes wouldn't be doing any the work. The cart would be cause it would essentially just be one of those systems crammed into a cart. Only power and controller input would be used from the snes. At that point why would you even wanna go through the trouble of developing such a thing when you could just buy a flash cart for the system you want do that? I understand wanting to have everything one on system. It's convenient but what you're suggesting isn't just practical.

I will end this by saying first and foremost I am not a programmer or hardware designer of any kind. I'm sure anyone with the expertise and knowhow can explain in better detail if there is any hope or not for anything you suggested. Anyway I encourage anyone who is capable of this kind of stuff to always be striving for more cool and interesting ideas and am grateful to be able to partake in there hard work. You guys are legends in my eyes keeping these old systems alive.

Me too please Gumball.

Thank you in advance.
This topic is getting a bit sidetracked with the requests for the Sufami turbo roms. From now on if you want them PM me Or click Sufami Turbo in my signature. No need to reply to this topic.

ah ok perfect!
This is my bios list: https://i.postimg.cc/xjwkXX8B/Immagine2.png

Do I need additional bios files in othjer to play every supported game?
the sufami turbo roms I have have the bios embedded into the roms them selves so no additional files are needed. I sent you a PM.

Any chance you could send me a PM too? The roms I have are from SM's pack but they don't seem to be complete.
It's sent.
Can i get a PM as well? :)

Should be a couple of weeks. Pev will refine the code and I'll test everything on the audio side of things with regard to editing and balancing.
Sounds incredible. I hope y'all will look into the possibility of reducing/eliminating the load times (especially the one right after "FIGHT!"). Even if not, I'm pretty psyched though.

Wow, I didn't know this. Not that I care that much, mind you (well, I am a little tempted to see if the Gegege no Kitaro game is any good), but any news that compatibility is even higher than I thought is good news.

Edit: Yeah, on looking into the Gegege no Kitaro thing, it doesn't look too great, so I stand by my original stance of not caring much. :P
from what I understand there are at least 2 different sets of sufami turbo roms. ones without the bios embedded and some with. I have the ones with. The ones without do not work on any flash cart. The ones that do have the bios do work.

Really great news! Now all EU and USA games are supported!  If i'm not wrong now these chips are missing: Sufami Turbo, SA-1, ST-011, ST-018, SPC7110 and Carts with BS memory pack slots.

In order to play SDD1 games it will be released a new firmware update? 1.9?


For sufami turbo you can actually just find the roms with the bios for the sufami turbo embedded. They run fine on my sd2snes. When you start a game it shows the sufami turbo logo and jingle then the game runs. I've tested all sufami turbo games and I haven't had any issues. If anyone want's them I can upload them somewhere.
