Re: read rom from SD card on SNES

I confirm that we would like to read a rom on the real hardware by loading it from SD Card (like sd2snes or everdrive proejct).

If esp8266 is slow for this kind of things, i need to search on internet other way to do it.
Any clues will be welcome !

Re: read rom from SD card on SNES

ok thanks, we are in 1st case (lorom without floppy copier header). But one point is not clear because no$sns provide the value on $00FFFC, like for hirom game. maybe emulator transform data to get common range between lo and hirom... To avoid an out of range address, we did a check for the value : ...

Re: read rom from SD card on SNES

We tried with this online editor
https://hex-works.com/eng
then with Sublime text (0xFFFC and 0xFFFD) but they both return 0000.

With no$sns, we saw that the value is b780.

Why value are differents between hex editor and emulator ?

Re: read rom from SD card on SNES

Hello, Sorry for the late reply but we are still working on this project and we didn't find why the rom is not loading. In fact, i think we need to know the entry point of the rom. Do you know which adress is the first called by the SNES ? With it, we will better undestand what are these address. Th...

Re: upgrade PVSneslib with wla 9.8

New try... I did a lot of test by reducing the code, replacing names, removing all "_" at the beginning of names, creating unique names for each section but i do not have anymore idea or things to test. I reduced the hello_world to this code (which work with wla 9.4) : #include <snes/console.h> int ...

Re: My Project : Super Papi Commando + SuperDan

Today, we do not have a lot of choice of engine for SNES without beginning from scratch.

PVSneslib seems to be a good way but miss improvements these last years.
If your engine is enough generic to create games, it could be an alternative or more a complement (because of C code).

Re: upgrade PVSneslib with wla 9.8

I changed a new time the title of this thread to be more precise. Few modifications have be done in wla 9.8 to solve some bugs and to add new functionalities that were coded for the specific 9.4 version used with tcc816 and snessdk. I think that wla 9.8 and tcc816 are now ready to work but i need to...

Re: My Project : Super Papi Commando + SuperDan

Hi !

You said in first message that you think to put your engine on github.
When do you think to do it ?
I will be happy to see what is the complexity to use it and its capabilities :)

Re: [SOLVED] upgrade to wla 9.8 when using tcc816

Now, i would like to compile a hello world project based on pvsneslib which use files that comes from snessdk. I created a minimal project...

Re: wla BACKGROUND and OVERWRITE directives with pvsneslib

I checked other directives in wla documentation ( https://buildmedia.readthedocs.org/media/pdf/wla-dx/latest/wla-dx.pdf ) and i thought to workarounds to do it like : - .UNDEFINE at the first step of header (of game project) then to keep the rest (i hoped it will change existing values) - Append in ...
