Re: controller auto reset

. That 1/60th second delay is critical to some pads. Now going longer is fine - for example, if your code loops once every other vblank, you know you have about 1/30th sec, which is way more than needed. Then it's not so critical. Which get back to my initial question ;) Some pads (third party?) au...

Re: Sega CD Mode 1 support functions for SGDK

This is another problem. The Mega CD docs feel like a trainwreck compared to the Mega Drive docs, information is either spread all over the place (often in irrelevant locations) or outright missing making it a freaking pain in the ass to figure out how anything works at all. I still can't remember ...

Re: Sub Header

After some times thinking on it, it's clearly a bra that we need.
If you exit, it means you can only handle ONE command per VInt => when the main( ) starts

so let's keep the loop ;)


And I really like your idea...it would be very useful for a Mega(CD)Games compilation ;)

Re: Sega CD Mode 1 support functions for SGDK

If I remember, you already answered to Sik on Sega16 back then, when you released your Mode1 demo ;)

(I read a lot on this topic lately, it's how I know!)


And, to the topic, it's exactly what's I'm doing this week ;)
RAW port was done, I'm trying to make it clear and easier to use before release

Re: Sub Header

Shame on me...everything I was looking for is on the MEGA-CD BIOS Manual, starting at page 30 :oops: I thought it was only the bios calls :( For main(), what's the better use then ? to loop on it (bra _main) or to exit and wait for next int2 ? From the manual, I would say exit and wait, but none of ...

Sub Header

Where could I find info on the SubProgram header ? I saw nothing on the official doc on how to write a sub program, starting with the header.... For ex, what's the difference between SPInit and SPMain ? Does SPMain mean to be called after a Reset (using register $A12000) ? Is there 3 , 4 or more jum...

Re: Convert atari st ym sound

I think, now rereading my code and based on your comment, the *PAL and *NTSC thing is prone to confusion. This define the clock rate (and not the rate) of the CPU used to render the sound It's to convert a sound coming from any CPU to the z80 : 3.579545 MHz (NTSC), 3.546894 MHz (PAL) So the 50/60hz ...

Re: SEGA CD Mode 1

Since this thread get some new coverage, I tried myself to make SGDK compatible mode 1. I go up to the sub run, then, I activate the vint synchronize thing and everything crash.... Probably something on my code but I don't know how to debug this !!! It seems Fusion and RetroArch support this boot fr...

Re: DIY controller not possible with AVR ?

oh...so trying to handle everything with the µC isn't always a good idea ;)

But using a multiplexer, I don't see how you could force your own peripheral ID, like I asked on the another thread...

DIY controller not possible with AVR ?

Hi, i was about to make a secret-product-to-Genny joypad when I read this interesting post of raphnet So it seems you can't make "easily" a home made joypad with an avr (read arduino too)... what do you thing of his experiment ? Does it mean you need a better µC ? or just avoid AVR ? What's bug me i...

Ok, I found you use the saleae software.
Did you try the i2s plugin ?
