In wiring my 32 Mbit flash.. I feel that I may have to wire another decoder to see if A15 is high -> Enable ROM again/disable /CS and vice versa.. does this sound about right???

Ok something new I don't understand. Teh SRAM is decoded to $70:0000 Now, with the address decoder operating the way we have shown, how is the ROM getting mapped at $70:8000?? I ran the super mario world in Super Sleuth and the bus shows ROM there.. Is this correct?? But how? The address decoder che...

thanks tepples.. ^_^

i have tested my prog on real hardware too mate

o.m.g it's for the MAD-1 .. ok got it

but 32 mb on lorom? how? This is truly "mixed" lorom+hirom correct?? why not just hirom??? They must be accessing lower half of banks $40 upwards. well really $C0 upwards cause its fastrom..

I don't get it... Isn't that what LoRom is all about, neglecting A15? http://www.snescentral.com/pcb.php?id=0885&num=0&side=front First thing I thought was that it is Fast ROM so it must be using the extra banks at the end for 32Mbit.. But you can see on the cart that A23 is Not Connected, s...

Shiru, I made a Test program that is a GUI for the Nintendo Sound Driver called 'Kankichi' YOu may find it useful.. Try it out.

You can play with the DSP register and see visual data real time on the SNES...

kyuusaku, that is great thanks, I want you to hear about my project. I have a Gameboy Cartridge Flasher that uses USB. and I am trying to forward thru an MBC5 cartridge to SNES connector so I can operate my own custom Flash cart. Before I do that I am trying to read the ROM header on my Super Mario ...

you are talking as if we are programming from inside SNES.. No, I am using a device which I plug my SNES cart in to read the ROM.. So I am wondering what the ACTUAL rom address are..

if they are different, I want to know the process SNES uses to map memory, I want to know how Address Bus is used...

The memory map is determined by the hardware that decodes signals to know what hardware needs to respond to an address. LoROM maps 32K banks in each bank. HiROM maps 64K in each bank. However in certain banks (banks under $80?) I think only the last 32K of each bank is available. Meaning if you acc...

infinitesneslives - i follow except on the part that explains CE vs. A15. Maybe explaining why A15 is used in HiRom would help??? tepples - sorry, not familiar The thing is that I have never actually learned about memory mapping address decoding etc etc. till the past couple weeks working on this el...

and as far as Lorom, what further confuses me is that A15 is NC (which is kept permanent high?) So how is it so that the ROM address $0000 is used? wouldn't it always be $8000+?? or is it the other way around and ROM xx:$8000-$ffff can never be accessed??

I am asking a quick question ( i believe ) What is the correlation between actual address in ROM chip in comparison to SNES Mapped ROM address, and what is the explanation behind this correlation??? I am not sure if / how / why in a LoRom model, the rOM at $8000 in SNES map is from actual ROM $0000....
