pokey - POKEY
| ||||
概 要 | 16ビットモードでディストーションの再生が不正確。 | ||||
詳 細 | The issue arise when using some distortions values in either 8-bit or 16-bit modes. When using the pure tone setting (AUDC0=$Ax or $Ex) it sounds fine; however sound problems are present when using other distortion settings on AUDC0. Values from $2x and $Cx (12a and 12b) in the attached spreadsheet (See zip archive file 'pokey notes.zip'), provides inaccurate results every time. | ||||
再現手順 | The issue occurs for any platform utilizing POKEY chip in the ways mentioned in the aforementioned "Description" field. Nonetheless, A7800 examples are provided in this report. Just load the ROM(s) contained in the zip archive(s) and playback accordingly. Take note of the real hardware POKEY captures compared to what is heard for POKEY emulation under MAME from the wav files provided. | ||||
