I also like the idea of lower case for Saturn peripherals. And yes, absolutely nothing in the header matters in the slightest for actual hardware other than the "SEGA" at 0x100, and that's only if you don't have hardware on your cart that allows bypassing the TMS protection like Jorge's carts.

I certainly hope you're talking about in the game as none of that applies to Mars in real life. :lol: Assuming Mars had a reasonably thick atmosphere that humans could breath, the only difference between Earth and Mars during the day would be the absolute brightness, and Mars has an intensity that's...

Using a camera and a processor to track the TV as the gun shifts is a good idea, but you can't count on the output of various TVs across all games. My own thoughts on the matter was to put reflective tape on the corners of the TV, have an IR LED on the gun, and put an IR filter in front of the camer...

Why make the slave soundless? Mix it with the other MD either via the video mixing section, or using the audio in lines on the cart of the master MD. Two YM2612/PSG would be VERY helpful for games.

Looked at the YT video - half the LEDs are covered by the console when plugged in! That wasn't thought out very well. He should have made the cart taller to compensate.

You want an AD8188 or AD8189.

That will do the RGB switching. RGB to component/composite are a dime a dozen. So no, there's not one single chip that can do both, but two small chips can handle it just fine.

Remember this table in MD work ram... ; OS system RAM assignments ; jump table ; vector table is 6 bytes each, but an address only needs 4 bytes. ; Each table entry contains 2 bytes of table data and 4 bytes of ; address. In other code, when you see these vectors accessed, they ; will always be acce...

Nice! The voxel part in particular.

The main issue with switching controllers between the Amiga and SEGA consoles is SEGA swapped pins 5 and 7 compared to all other 9-pin controllers to avoid patent issues. Yes, the original 9-pin DIN controller interface everyone (but SEGA) used was patented. I've moved SEGA controllers over to the A...

The table starts at 0 and goes to 1023. 0 binary angle units is the same as 0 degrees, 256 is the same as 90 degrees, 512 is the same as 180 degrees, 768 is the same as 270 degrees, and 1024 would be the same as 360 degrees. You AND the binary angle you are using with 1023 (0x3FF) so that anything m...

but it seems every game reinvent the wheel every time...for every thing Unless you license engines and libraries (if the library needs to be licensed), you WILL reinvent the wheel on everything. It's inescapable. Generally, I borrow a lot from my old code, depending on if my current employer owns t...

Why 64 to -64 ???? I read that sinFix16( value ) needs a value from 0 to 1024, I just put 'x' and works... not sure why :P It goes from 64 to -64 because with the fixed point 16-bit numbers in SGDK, that's 1 to -1. Remember, the fractional part of the fix16 is 6 bits. The table goes from 0 to 1024 ...

I love how in the jukebox, the game character are playing the instruments.

Thanks for posting that. There are plenty of people who use BSD, so I'm sure others may find that handy. In any case, SGDK is a nice devkit. I contribute to it myself. It's more for people making MD/Genesis games who want/need a lot of functions to control it's many features. To the end, it's great....

Okay, had a chance to look at my track ball this weekend. Took the opportunity while it was apart to clean the ball and rollers. Anywho, my current belief if the problem is low voltage. Vcc at the MCU is only 4.64V. On the CDX, it's 4.86V. While the datasheet for the MCU says the minimum operating v...
