The proposal about a SDL port

Hi,

 

there is a point which is individually worrisome about a SDL port.

 

 

Please change into the configuration file name different from original VisualBoyAdvance (For example, vbam.cfg). It is not compatible with original VisualBoyAdvance.cfg.

Thanks for your changes. This is indeed more correct this way, commited to SVN.

If you want to submit some more patches, please attach them as files. Copying and pasting broke the patches and I had to apply the changes manually.

Thank you, it understood about the presentation method of the patch. It supplements.
