Re: Interest in "modern" SNES Development Hardware?

One thing C is supposed to do better is make it so that when you fix a game logic problem on the Genesis version of a game, the same problem is fixed on the Super NES version as well, and vice versa. You wouldn't get nearly as many PS4/XbOne/PC cross-platform releases if porting game logic involved...

Re: Interest in "modern" SNES Development Hardware?

I go with what koitsu said. I can not really agree on the missing C compiler being the main reason for lacking homebrew (or interest in programming for the system). Though it would certainly help getting started without knowing asm, I would say an assembler with a good set of basic macros would actu...

Re: Interest in "modern" SNES Development Hardware?

Yes mainly: A graphic tool for converting bmp/png files (Tepples made one but it has Python dependencies) to the SNES formats, free music engine (if it doesn't already exist), Nerdy Nights-like newbie tutorial. For graphics conversion I use SnesGFX , it does output a map file for backgrounds and pa...

Re: Interest in "modern" SNES Development Hardware?

@93143 I considered in your reply that you already did get started to develop something, so for you the issue was the missing accuracy in the current emulators (though you really try some crazy things :D). But there were several other posts that bassically said, that getting started with SNES develo...

Re: Interest in "modern" SNES Development Hardware?

Though the talk got pretty much offtopic to whether or not the lag is perceivable or not, I guess from the answers before, it seems emulators are enough to debug developed SNES software.
There is rather a need for Software Tools to get easier into developement of SNES games and software.

Re: Interest in "modern" SNES Development Hardware?

@koitsu:
I can approve of the SD Card Interface not being too easy, I have a 1000 line state machine just to read the first sector of an SD Card (this includes calculating the CRC and initializing the SD Card).

Re: Interest in "modern" SNES Development Hardware?

@Kismet: I have done some more research and it turns out I would need a better, more expensive FPGA to drive a DVI or HDMI signal. The Cyclone II does not have the required TMDS Interface, and LVDS seems to be not suited to drive TMDS. And if the FPGA had the TMDS Interface, it would allow only for ...

Re: Interest in "modern" SNES Development Hardware?

I have mistakenly assumed ca65 compatibility would also apply to cc65.
However I have seen WDCTools is available for free, that would at least supply you with an additional IDE.
Other than that, it seems that tcc-65816 is the only open source solution available?

Re: Interest in "modern" SNES Development Hardware?

I would implement any feature thats within reach. For example i wanted to support partial SA-1 and SuperFX developement Features (if that is possible) by loading a program into the WorkRAM of a Cartridge, that should allow the processor to execute anything loaded in there. You could then write your ...

Interest in "modern" SNES Development Hardware?

As kind of a response to this thread , saying: [...]Is SNES homebrew dying, yet again?[...] Would some SNES Development Hardware revive it? I am in the process of designing Hardware, which could evenually end up to be a "modern" version of the Super NES Emulator SE (even though I can only imagine ho...

Re: Questions on SNES APU Hardware

nice example, so this actually does exist (even though its just a proof-of-concept).
But you are right defparam, when intercepting the /PARD and /PAWR signals on the hardware side, it wouldnt matter anyways how data is transferred.

Re: Questions on SNES APU Hardware

Also, I don't believe DMA is used to communicate to the APU. If you look at the IPLROM disassembly it is a bi-directional handshake to transfer a single byte from the CPU to the APU. Even though many games would use the IPLROM to transfer Blocks of data, there is still the possibility of implementi...

Re: Questions on SNES APU Hardware

@defparam The Idea in Edit2 actually sounds really good. I could just implement the SPC700 processor part and ditch the DSP (i could use an existing 6502 core as the base, but there are additional conditions needed to be worked in, in order to replicate the SPC700). It would need to keep track of th...
