Hi!

I am sorry to put this here, but I cannot use the SourceForge report utilities because at the University we are not allowed to use cookies.

openMSX does support WAV files with unsigned 16-bit values, but does not accept signed 16-bit values. For example, frequencies 8000h and 7FFFh will be understood as 32766 and 32765, so the file will not load.Hi!

Apart from this, I have discovered that the MSX1 VDP emulation is not accurate. I cannot exactly say where is the problem, but I have got some code here that crashes on MSX1 computers but works fine on openMSX in MSX1 computers. I can send it to you, if you want, and let you know my impressions about what is wrong.

Keep doing that good job, guys!

Please send us an e-mail with the details and the code (if necessary) to openmsx-devel AT lists DOT sourceforge DOT net. You can always use that, no matter if you are allowed to use cookies. Please do that in stead of posting on MRC, you will be sure to reach us then.

openMSX uses the audio facilities of SDL. I think Wouter can comment on this.
We know that there are some timing problems in the openMSX CPU or the MSX1 VDP. E.g.: Zanac shows a currupted intro screen. It is possible that your bug is also related to timing details.

I guess that it should be

openmsx-devel DOT lists AT sourceforge DOT net

Am I right?
