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 !

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 : ...

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 ?

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...

Hello, We are trying to create a rom reader for SNES and have some issues. We are using pinouts informations from here : https://www.caitsith2.com/snes/flashcart/cart-chip-pinouts.html On snes maskrom, what is the goal of /OE (pin 31) and /CS (pin 22) ? Do you confirm that : - /CS means address is r...

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 ...

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).

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...

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

In fact i still need help :) I built tcc816 with latest wla dx version. But the initial tcc816 was provided with a special wla dx 9.4 and had some modifications. 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...

Hello, I think tcc65816 provided with Snes SDK has its own version of wla which has been modified to work with it : https://github.com/optixx/snes-sdk I would like to upgrade wla (version 9.4) to the latest 9.8. I tried to compile a simple hello_world (i saw that parameters change) but i get this er...

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 ...

Thanks for these informations. I juste tried this code but my issue is still existing : i get few release states when button is pressed. So i investigated on the second solution to understand (with autoread bit in NMI) and it seems to be already implemented in the lib : I saw this in ConsoleInit() f...

I hoped it was only a line to change!
I need to learn 65816 asm to do this because i don't know how to implement it.

Thanks for you help

I add few informations. This is the main.c file generated to asm file, juste before using wla: .include "hdr.asm" .accu 16 .index 16 .16bit .define __main_locals 2 .section ".text_0x0" superfree main: .ifgr __main_locals 0 tsa sec sbc #__main_locals tas .endif jsr.l consoleInit __local_2: lda.l pad_...
