To force C++11 you need to pass your compiler the -std=c++11 or -std=gnu++11 flag in your makefile rules. I don't use DreamSDK but I would imagine there is a makefile definition somewhere like CXXFLAGS += "blah" where you can add -std=c++11 or -std=gnu++11.

Not at the moment, but maybe in the future. I think it's better to keep stuff like that someplace like here, since the Internet Archive can find it and it's less likely to get lost than a proprietary, closed site. I get that too, a vast majority of help I've gotten from DCemulation has been relativ...

With careful management, you could theoretically access 4 banks of memory simultaneously with minimal performance penalty as each independent ram chip has a single sense amplifier that covers two 2048kb banks each. Would you mind clarifying this? I thought that regardless of the physical ram arrang...

I'm not sure that method is a good way to do it. Manually setting addresses of variables in the linker script seems error prone, and I'm worried that GCC will overlap variables in RAM this way. For example, if a large normal, cached buffer is declared, and gets placed to it ranges from 0x8c100000 t...

I wanted to take a quick second to, in an abridged manner, show how you can make sure a variable is defined where you want it to be at an absolute memory address. The advantage of being able to do this is that you can define multiple memory blocks at specific locations to prevent them from destroyin...

Thank you so much for not only diving into this topic, but keeping the thread updated with not just your successes, but also your failures. That stuff helps so much, there have been so many topics that I've been able to work out only because decades ago some people took the time to document their ef...

there is a libary in kernel/arch/dreamcast/include/dc that is intended for scif (serial communication inferface with FIFO). Here is the header: http://gamedev.allusion.net/docs/kos-current/scif_8h.html And more appropriately, here's the source, as used by dcload: https://github.com/Kochise/dreamcast...

Holy crap that is kind of awesome. I wonder why no games used it. A few games do in fact use it. The best known example is this coin in Shenmue 2: https://i1056.photobucket.com/albums/t366/Esppiral/REVERSO_zps59210cb9.gif The technique is also outlined in the official Dreamcast development manuals:...

You can render to a framebuffer texture, then rotate the texture, which would rotate the entire screen, but be aware that rendering to a framebuffer on the dreamcast consumes an entire vsync cycle. This is because you command the PVR to draw to the texture, and the PVR draws at vsync completion, so ...

What do you mean by "rotate objects"? Do you mean, rotate the texture on the polygon you are drawing, or do you mean rotate the entire polygon? Both are done in the draw_sprite() function according to the tutorial. A polygon is defined as two vertices in the example: float x0, float y0, fl...

There are multiple ways to accomplish what you are describing, and how you accomplish them will radically change the behavior and what is being demonstrated. If all you want is some text on your screen, the easiest way to do this is to use the bios font. The example for this is is under kos/examples...

Making stand alone VMU applications is exponentially harder than even writing a dreamcast application to control the VMU in-controller. You'll either be writing it in LC86000 Microprocessor assembly, or you're going to write it for an embedded ARM Cortex M32 emulator (https://dmitry.gr/?r=05.Project...

This question can be parsed in a number of ways. Do you mean how to animate the screen of a VMU that is currently attached to a Dreamcast controller, through a homebrew dreamcast title? Do you mean how to create a stand alone VMU application, and manipulate the VMU screen to produce an animation? Or...

I see you are having problems in this and the other topic you made, and both stem from the same misunderstanding. Let me give you a quick primer on folders and command line interfaces in both windows and linux. When you issue a command from the terminal, what you are doing is calling out to a specif...

the KOS toolchain should have built sh-elf-objcopy. Use the following command to convert the elf to an unscrambled binary: sh-elf-objcopy -R .stack -O binary file.elf file.bin If you wish to run the binary from an actual CD, you'll need to scramble the bin first using scramble from the KOS utils fol...

so just a heads up, following up on this, using sh-elf-objdump and looking at the disassembled code that gcc spits out after compilation, it seems the counter is indeed behaving correctly. O3 optimization makes judging the order and count of cache misses (and other countable occurances from the perf...

I want to be able to detect cache misses so I can better profile some code. I see DreamHAL has a perfctr module that looks like it can count cache misses but I'm not sure how to read the results correctly. It appears that you can dedicate one of the two perf counters inside the SH4 to various tasks ...

So I sat down and decided to try and adapt this to work with windows vscode while writing a tutorial to get it all set up. Thus far everything is straight forward, except I'm having an enormous amount of trouble actually generating sh-elf-gdb.exe in windows with python support. MingGW includes gdb.e...

This is terrific! I've gotten all this stuff going with QTCreator before, but I know way more people use VS Code. Thanks so much for this tutorial!!

that guide is super super out of date. I've actually rewritten the setup portion many times since then, those instructions outright don't work anymore. One day I'll post the updated version once it's finished.
