# Known PSn00bSDK bugs
This is an incomplete list of things that are currently broken (or not behaving
as they should, or untested on real hardware) and haven't yet been fixed.
## Libraries
`psxspu`:
- Calls to `SpuSetTransferMode()` are ignored. SPU transfers are always
performed using DMA, which imposes limitations such as the data length having
to be a multiple of 64 bytes.
`psxetc`:
- `DL_LoadSymbolMapFromFile()`, `DL_LoadDLLFromFile()` and `dlopen()` have been
disabled due to bugs in the BIOS file APIs. The dynamic linker can still be
used by loading DLL binaries into RAM manually and calling `DL_CreateDLL()`
on them (see the `system/dynlink` example).
## Tools
- The `mkpsxiso` submodule is temporarily set to point to a fork of `mkpsxiso`
with bugfixed CMake scripts (the main repo is broken to the point it fails to
build). There is [another fork](https://github.com/CookiePLMonster/mkpsxiso)
which is currently work-in-progress and includes more fixes as well as a tool
to dump existing CD images: PSn00bSDK will switch back to the main `mkpsxiso`
repo once the changes get upstreamed.
## Examples
- `cdrom/cdxa` and `sound/spustream` demonstrate how to stream an audio file
from CD-ROM. Such a file isn't provided however, as PSn00bSDK does not yet
come with the tooling required for transcoding audio from a source file. In
order to run these examples you'll have to provide your own audio files,
convert them and build the CD image manually.
- `demos/n00bdemo` suffers from flickering on real hardware, especially when
masking/stencil buffering is used.
- `graphics/render2tex` gets stuck after initialization on real hardware.
- `io/pads` seems to work on real hardware, but fails to automatically enable
analog mode on DualShock controllers. This example needs more testing with
official and unofficial controllers.
- `io/system573` hasn't been tested on a real Konami System 573. It runs on
MAME, however MAME's System 573 emulation is *very* inaccurate.
