Re: Cart Design Questions

Thanks guys, your help is invaluable. Great news on the Z80 also pulling /TIME low when accessing the /TIME data range. That means that the Z80 can send "play sound" and "play instrument" commands to the ARM chip! I have looked now at using 3.3V flash on the cart pcb extensively. It seems that if th...

Re: Cart Design Questions

Thanks again Tiido for your advice. IT appears this setup is no-where near as simple as I was hoping it could be! But I thank you for taking the time to advise me, I really appreciate it. You are correct about the sellers on AliExpress - it turns out they are not new parts, but pulls. However there ...

Re: Cart Design Questions

Thanks guys, Re: Chilly Willy, I did read the datasheet, but didn't understand that would happen. I scoured the doc for mentions of what voltage it would output at but didn't realise it would output at generally what is input. Fantastic! With 512KB of flash I hope that will be enough to hold all the...

Re: Cart Design Questions

Hi Tiido (and others!), I have done lots of research about possible cart design options, but I have a few more questions that could help me immensely! I think I have found the memory chip for code, graphics and music assets: the M27C322. Available for ~$1 on aliexpress, 32megabit, parallel, 5v, < 10...

Re: Cart Design Questions

Thanks very much for taking the time to help TmEE. I have done hours of learning since, and hope to post what I've learned plus a question or two later on, but it's not ready yet. But I have found 5V 32MBit Flash/Eeproms available, and a suitable DSP for augmenting the sound system of the MD. Just n...

Cart Design Questions

Hi all, I am hoping to get some feedback on the design of card needed for a commercial game. I am not ready to produce something, but I am the kind of person who likes to have most questions answered before starting something! I have more than a decade of programming experience, in pure C (Wii/PS2/P...

Re: How I can get started learning C and the SGDK?

Well, those programming books are probably a good place to start regardless :)

Re: Coming Soon(ish)... probably [Update - 15/06]

Count me in as well as someone interested, but I have a couple of questions - if you'd be kind enough to answer I'd be very thankful! Would the boards have all components soldered to them amushrow, or would we need to complete (+- including purchasing of all the components) the product ourselves? Al...

Re: How I can get started learning C and the SGDK?

Hi Scythe, Have you programmed in any language before? Or are you looking to learn your first programming language? I'm no expert, but my suggestion would be to learn C programming independently from Mega Drive games development. Once you are proficient in C programming, then try working with an est...

Re: Tanglewood - now on Kickstarter!

Matt, your work is inspirational. I hope to be able to make Mega Drive games in the future, and your work is like a blueprint of what to do! I'm looking forward to seeing the finished, crafted product at the end!

Great work guys on getting your Kickstarter going and your progress with the project.
All work (code, art and music) look stellar so far. I'll be following this closely!

Re: XGM PCM

Thanks Stef,
I'm glad to know it's at least possible!
I'll continue to make my engine in the background. Thanks for everything you continue to do with SGDK. :)

XGM PCM

Hi Stef (and others!) Just a question, when I make multiple xgms for use with SGDK, which all use the same rhythm drum kit pcm sound effects, and I combine them as assets into my ROM, do the PCM sound effects only take up space once in the ROM, or does each song have it's own instance of the PCM dat...

Re: Make a wish / What if : Genesis

Hmm I seem to remember reading somewhere that if the Master System video mode was sacrificed, there would be enough CRAM available for more palettes, or something similar to that. Never mind! And I definitely wouldn't want to sacrifice 320px wide mode - that is one of the killer advantages the MD ha...
