Now that Guy’s document is available I can’t see any reason to keep the wiki where it simply duplicates DT’s out-of-date document, the V810 manual, or the development manual. Any original wiki content can be archived. I’m on board with repurposing the wiki as a comprehensive Virtual Boy programming tutorial.

The PAL SNES power adaptor is AC so it shouldn’t really be used with the Virtual Boy which takes DC. I’d get a japanese adaptor tap (which takes a 5.5 x 2.1mm DC jack) and the EU version of this adaptor (I have the UK version):

Something else. Possibly a scatch or dust on the display window, lens or mirror. See also:

A workaround for this bug is to compile with -mno-prolog-function.

If you haven’t already, ask the seller to remove the listing.

I’ve reported the listing under the category “copyright and trademark” as a replica item, the listing of which is against ebay policy.

I don’t think you’re using the fixed linker script, or you wouldn’t be getting the undefined reference errors to __gp and __data_start. In your makefile specify the linker script you want the linker to use with the -T option, e.g. -Tpath/vb.ld.

I’m not sure why you’re getting the undefined references to memcpy. Are you including string.h in blox2.c?

Hi. Try compiling with the linker script and crt0 attached to this post. This should fix the overlapping sections error.

Nice work.

Which bitstring instructions do they use?

Hi. This tripped me up too. It turns out only the even byte addresses in SRAM are accessible. The Flashboy has 8K of SRAM.

There’s also the 2×30 connector that Vaughanabe13 found:

Hi. It may be that the crt0.o you’re using isn’t setting up the column table correctly. Try the one I’ve attached.

You’ve fixed the slowdown, but not the graphics corruption. The backround isn’t displayed correctly on the right screen, and there’s no sound.

Try using the version of libgccvb included with the drawsync demo.

Hi. Try compiling the demo attached to this post. Make sure the path is correct in the makefile. What happens when you run make from the cygwin command prompt?

Akumie doesn’t have the Mario demo. See this post.

I don’t know if this helps but here’s a Virtual Boy pinout from:

FuriousJorge, what version of the compiler are you using? What errors are you getting?

jzagal, try compiling the attached demo. Make sure the path is correct in the makefile. Then open a command prompt and run ‘make’ in the drawsync directory.

HorvatM, blitter has also written a clear and detailed description of the VIP drawing process in his wiki article on direct screen drawing which you may find useful.
