Thanks for the info about the 32x! I'll take a look at the link as well Thanks dude

Hey everyone, I have a few questions about the Genny/MD: Question 1: Is there an easy way to determine if a Game Genie, 32x, or Sega CD is attached to the console? What about copiers? I'd like to put in some commands or functions into SecondBASIC that would return a 1 if the above is detected, and a...

oooh, more links to check out :D Thanks! I do have a couple of questions: I've been rebuilding my BASIC compiler using BEX's ASM Library (devster gave me the go-ahead to use it :D) and there's a few things in BEX that I don't understand what's happening, or rather, I understand what's going on in th...

Natsumi, Thank you for those links. I did look at... Yeah that's cool, give someone else all the credit, even though I did do a 5 paragraph reply with physical media and everything but no no, say thanks to the guy who gave a 1 line response. Anyone needs me I'll be over here eating worms. :P :lol: ...

ryanfaescotland, Thank you for those links. I did look at BigEvilCorp's blog (very awesome, as well), but I couldn't find the stuff that I was getting confused on. His blog will definitely be referenced more as I learn ASM better. Natsumi, I've also used Marky Jester's tutorials a lot, which is why ...

The example code you have would do this move.l d0, -(a2) // moves the 32-bit value in d0 to the address pointed to by a2, decrementing it by 4 before addressing move.l d2, (a4)+ // moves the 32-bit value in d2 to the address pointed to by a4, incrementing it by 4 after addressing the increment/decr...

I've seen a few tutorials here and there that have been very helpful in learning some of the more basic op codes and working with data registers, but I haven't found much in terms of using the address registers. I guess what I'm asking for is almost a "hand held" (I really hate that term) tutorial t...

My question is: Does the size of the SRAM file that Fusion creates (or I suppose every emulator creates) just depend on how much you utilize the SRAM (like, if I only write 6 bytes, the file will be 6 bytes), or does the file get padded based on the size in the header? Or, does the size in the head...

Thanks Eke!

Natsumi, a big thank you for pointing out the dc.l $0000 after the SRAM portion. That wasn't affecting the SRAM, but instead the region settings. Regardless, thank you for quickly pointing out that mistake :) I also tested the ROM in BizHawk (neat emulator, btw, thanks for showing that to me!) and i...

Eke, thank you for that wealth of knowledge. My plan is to support standard usage of SRAM so any compiled rom could use any general sports game as a donor pcb (and my SRAM pcbs that I had designed and made up, which supports ODD, EVEN, and BOTH; tested using BEX and all). I still have some confusion...

I can tell just looking at it, the SRAM header is wrong. But fear not, as for most emulators this does not matter. This is also why the Fusion .srm file is usually only so large as you have written to it, rather than the intended size. There is no way to force this, other than to fill it completely...

Also, isn't backup ram the same as SRAM? If not, what are the differences? (Sorry for all the questions!)

Okay, so the hardware and emulators don't care about the header as far as SRAM is concerned? Am I understanding that right? So if I want to use SRAM on the hardware, is all I need to do is read and write to the desired locations (say at &h200000) and if the pcb is wired for it, use even, odd, or bot...

I think I'm having a bit of misunderstanding with initializing the SRAM in the header, and I'm hoping one of you more experienced programmers can help me out :) Using the BEX ASM library and this wiki article: https://en.wikibooks.org/wiki/Genesis_Programming , I've attempted to set the header up wi...
