Suddenly SGDK refuses to compile and run the bin, and for some reason resources.h has a squiggly line underneath it. #231

Hey folks,

Sorry for the lack of organization, new to both SGDK and GitHub. Anyways, I was doing some tutorials and everything worked fine, but out of nowhere I got a squiggly line under resources, have not been able to compile and run the emulator from the ctrl+shift+p shortcut, and I get this massive list of issues in the Terminal. What am I not understanding here that is causing all this, because I haven't really deleted or tinkered with anything.

Thank you for your time, cheers.

Note: I tried compiling my first tutorial project, and it worked fine, so this is surely a problem specific to the current project. Hope this helps!

Also, Stephen. I'm an indie dev and would love to be able to make a future game on the Mega Drive alongside modern systems for my future projects, and using the MEGA CD in some capacity would be a dream, so is there any chance of an expansion to the SGDK library to be compatible with the MEGA CD in the future?

With Terraonion's Mega SD and Krikzz EverDrive, development and testing on actual hardware is now a genuine reality, so I'm curious to know what you're thinking there.

Finally, what is realistically, the largest size a Mega Drive rom file can be? With EverDrives, we're no longer confined to 4MBs, so what would the scientific limit be? I'm asking in case the MEGA CD option is out, we could just take the SNES EverDrive SD card extra capacity approach if that's possible.

Sorry for all the questions, but its been a very exciting week for me working with this thing and a life dream is now a genuine reality thanks to you!

Hi @thinkOfAnAnswer

I don't know which tutorial you followed but the #pragma region error you got is really weird for the least, does your code really contains #pragma keyword ? this is really low level C stuff and you shouldn't need that with SGDK.

For your second question, lot of people already are asking for MCD support in SGDK. I will be honest, this is not a priority feature for me. I eventually will add limited support to it (just to use CDDA for instance) but i still give priority on Sega Mega Drive / Genesis first. 4 MB ROM is the maximum without involving bank switching mechanism, with bank switching (SGDK provides SSF2 mapper support) you can go higher than that, i would say the theoretical limit is really high (128 MB) but realistically when you're using the SGDK embedded mapper support, 16 MB is probably the maximum you can get (because all common data and all resources metadata have still to stick in 3 MB limit).

If you want support about SGDK in general, you 'd better join the SGDK Discord server Lot of people to help you there, much better to get support. You can also use the SpritesMind forum if you don't use Discord as Github Issues are more about submitting bug with SGDK :)

Hey Stephen,

I'm using the OhSat tutorial list (MegaRunner project), but the game runs and compiles fine, its this specific project that won't compile and run from within VSC.

Can the pragma region lead to issues like that? Why is ignoring it? Does that also include the code inside it?

"this is really low level C stuff and you shouldn't need that with SGDK."

I'm fairly new to C so I thought I'd organize and make things cleaner for me to see and read. What if my project increases in scope and things get a bit on the messy end (I get lost when the page is full of code and you have to keep scrolling down), how would I make things in smaller chunks? Would I write the entire project in the main.c file? I guess what I'm asking is, how would you divide this into smaller chunks?

I'll be sure to join the Discord community, sounds like a great resource to lean into.

Thank you so much for your time, Stephen!
