2013-03-16Ship by default a free DSP ROM that can handle most games with LLEPierre Bourdon
At the end of July 2011, LM published a free DSP ROM that works with games using the Zelda UCode. His ROM only has the code to handle UCode loading and a few utility functions, the rest is missing. This includes the four large sound mixing functions used by the AX UCode and the DROM containing coefficients used for polyphase resampling in AX. This is an improved, updated version of this ROM, which changes the following: - We now have a free DROM that works for polyphase resampling by "emulating" linear interpolation. The coefficients contained in the DROM are normally a list of { c1, c2, c3, c4 } which are used to interpolate a sample value from four previous samples: out_sample = prev1 * c1 + prev2 * c2 + prev3 * c3 + prev4 * c4 The coefficients are chosen depending on the fractional part of the current position (basically, our position between the previous and the next sample). We can use this fact to generate (c1, c2, c3, c4) for each possible fractional part so that: out_sample = prev3 * curr_pos + prev4 * (1 - curr_pos) Which is the formula for linear interpolation between prev3 and prev4. Linear interpolation is not as good as polyphase resampling but it still works very well and I couldn't really hear any difference between the two. If someone wants to generate real polyphase filter coefficients, they are welcome to submit a patch. - The IROM now contains the 4 mixing functions used by the AX UCode: mix_add, mix_add_two, mix_add_ramp, mix_add_ramp_two. They are large, inlined functions (probably for performance reasons) in the official DSP IROM, our version prefers to use a loop. This *should* be more performant with our DSP JIT implementation, but I did not benchmark that. Because the new DSP ROM is working just as well as the official ROM in 95% of cases, it is now shipped by default with Dolphin and will be used with DSPLLE if you don't have an official DSP ROM in User/GC. It will still display a panic alert at every boot to notice you that you are using a non official DSP ROM made by us, which is not perfect. Games using the CARD, IPL or GBA UCodes are still broken. I don't know what games this actually impacts, but this is a very small proportion compared to what works.

2010-06-02Meta:Soren Jorvang
Using Unix tools to operate on a tree containing filename with spaces in them is really annoying, so rename the handful of instances where there were spaces. Host.cpp has never been used. Games tend to lookup the following directories that we don't yet have anything to put in, so prepopulate them in Data/User/Wii: title/00010001 title/00010002 title/00010003 title/00010004 title/00010005 title/00010006 title/00010007 meta shared2/title Set eol-style native on a number of text files which didn't already have it. git-svn-id: https://dolphin-emu.googlecode.com/svn/trunk@5572 8ced0084-cf51-0410-be5f-012b33b47a6e
