I think the cart would have to be specifically made to work in SMS mode, but I'm not going so far as to say it's impossible. It might be possible that if you grounded the M3 select, and interleaved the ROM image to put the Z80 code on every other byte, you could run a non-bankswitched SMS game. The ...

My software doesn't pad anything, since erased (flash)EPROM already has FF in unused places... The padding could still be required, your eprom would be performing the 'padding'. What in the Genesis would require the padding? The checksum is software only. And would be affected by the padding only i...

The genesis hardware need a 128 KB size alignment or your rom won't work correctly. You said objcopy do padding, can it does size alignement which is somewhat different from padding (padding just fill until you reach the pad size where alignement fill until size align). Maybe some emulator or game ...

Can padding be handled in asmx? I tried: ds 524288-*,0 But, this only works up to 1024 bytes, due to the MAX_BYTSTR define. Upping the size of the MAX_BYTSTR would work, but there has to be a cleaner way. Like CW said, you probably want ORG $80000. At the very least, you shouldn't specify padding l...

While I still have a soft spot for 68000 assembly language, ARM most definitely does not suck. And it's used all over the place. Nintendo DS for games; most modern PDAs, even the granddaddy of all PDAs, the Apple Newton (and now the iPhone!); and lots of embedded stuff. If SuperH is so good, then wh...

Dual-booting is so lame.

Most new LCD and Plasma TVs allow you to change the overscan. Mine does, but I noticed that when it's on 0%, there usually is some black either on the right, left, bottom, or top. It's like the TV station itself has bad centering, and these were digital channels. (The HD channels didn't have this i...

I used something like this to program my GAL chip: CLK is the clock input to the SDA/SCL latches CLK = !TIME & !WR_L D7 input from SDA D7 = SDA D7.OE = !TIME & !OE D6 output to SCL SCL := D6 (latched by CLK) D7 output to SDA SDA = 0 SDA.OE := D7 (latched by CLK) and ROM_CE works just like it always ...

How should I do the wiring of SDA/SCL? to be like 1of3 methods? Look for the other threads on this. Fom the hardware side you need latches for both SDA and SCL, with the SDA latch controlling the tri-state input of a gate which outputs either a zero or a tri-state (or use an open-collector output),...

The main reason is that TV manufacturers are cheap, and manufacturing variations will make it too hard to align sets for perfect centering. But there is a subtle reason which is not obvious until you have the ability to center your picture horizontally. If you do that and rotate the TV 90 degrees, t...

And about those I2C/Microwire do the emus support them, is there any official cart with any of those, so it can be compatible with emus? No released games used Microwire, and no more than 20 or so (including 32X games) used I2C. Many emulators do not support I2C save memory, and even those that do ...

I've found that it's best to avoid using the top two and bottom two rows, and the left and right four columns on NTSC. That means keeping to 256x192 or 32x24 for anything important. It's not that you shouldn't use anything outside that range (it lets you avoid having a blank border), but you can't c...

It's very configurable. With logic gates. On the cartridge board.

There are no registers at $A13000-$A130FF. Not unless they are in a specific cartridge, in which case you should mention which cartridge you are asking about. /TIME is a chip select for the address range $A13000-$A130FF, just as /ROM_CE is a chip select for the address range $000000-$3FFFFF. I have ...

Thanks, except that PDF is evil. Only if you don't use a Mac. Adobe's PDF viewer and web plugin for Windows takes forever to start up, which is the true evil, but OS X uses PDF as its basic graphics model and comes with a viewer which supported it from the start. And this is nothing more than a bun...
