nesds's Issues

Mike Tyson's Punch Out - Glitched out graphics

The ring in Punch Out is glitchy on nesDS, as tested by SleepyLark. The reason seems to be PPU fetches. If the PPU does not fetch the 34th tile, the ring will be glitched. (Source)

I hope to add NESDS support for Chinese characters.

I hope NESDS will not display Chinese as garbled when reading Chinese name rom.（It would be great if there was a Chinese translation.）

Games won't launch, black screen

Launching nesDS the top screen just shows a blank black screen with no music. I can tap the bottom screen and use the menu fine.

Launching from latest version of twilight menu

System: DSi

Everything else works fine, slot 1 card, nds-bootstrap, other emulators

Tried launching the rom from the directory on twilight menu, and launching nesds then selecting the rom in the menu

Remove hardcoded offsets for mapper variables.

Use structs instead with correctly sized variables.

CIA file in 1.3d+ uses incorrect TID

TID for CIA included in 1.3d+ release uses incorrect app type setting. Game code not changed from default #### and app type is 0 which will result in 3DS TWL_FIRM trying to boot slot1! The resulting CIA file is not usable as a result.

Esper Dream 2, Mouryou Senki Madara and several VRC6 romhacks have sound completely wrong

Romhacks such as these:

• Mega Man RushJet VRC6 edition.
• Mega Man II RushJet VRC6 edition.
• super Mario Bros VRC6 expanded.

This is how Mega Man II VRC6 hack should sound as an example:

Barcode World barcode entry not working.

The entry of a barcode into game 'Barcode World' with the DSiXL does not work, I cannot test on any other DS to try it out.

I can enter a barcode into Dragon Ball Z: Gekitō Tenkaichi Budokai successfully, but the game Barcode World does not move when it gets to the Barcode Entry screen, it might be something to do with how the game stalls the processor, or keeps it from reading other ports until the serial data has arrived from the Barcode Battler.

APU Mixer - Entirely Incorrect

Comparing the APU Emulation between NesDS and real hardware using test ROMs show us that the APU Mixing on NesDS completely fail the testings and as such, is inaccurate to the original NES APU Mixing.

DMC Channel Test: Real Hardware | nesDS | Test ROM
Noise Channel Test: Real Hardware | nesDS | Test ROM
Square Channel Test: Real Hardware | nesDS | Test ROM
Triangle Channel Test: Real Hardware | nesDS | Test ROM

nesDS.cia not working

I have installed the nesDS.cia.
But if I run the software, it tells me, “A failure has occurred. Please hold the Power button to turn the system off.”.
If I run the nesDS.nds file over TWMenu++, all is working fine.
It is something that I do wrong ?

SRAM saves don't work when launching save-compatible games using arguments

Micro Mages - Sprite Rendering Hang

Tested by fghsgh on Discord, using the NesDS build provided on RocketRobz/NesDS. This game can be purchased for 9.99 on morphcat.de

it looks like it hangs the moment it tries to render the first sprites

I'd like to get confirmation of this though, considering I do not own the game.

Make all mappers that use MMC3(like) use the same code.

Separate the MMC3 code from mapper4 and into its own file, use this in all the other mappers that use MMC3/MMC3-like.

NesDS not working on Nintendo Macro with Twilight menu

NesDS has the ScreenSwap option, but this is ignored when launching a rom via arguments (like Twilight menu does). This makes it impossible to use NesDS on a Nintendo Macro, which has no upper screen.

I checked the code, the fix might be as simple as doing this in arm9main.c:

if(!bootext()) {
	//chdir("/");
	do_rommenu(); //show a menu selecting rom files.
}
else
	hideconsole(); // make sure all ini-file settings are applied.

But I am unable to check this, as I cannot get the toolchain to run.
