| 概 要 | オーディオDACの問題。 | ||||
| 詳 細 | William Schaub reported this issue to me after discovering the issue doing some software development. William's comments: "There are two programs on the 1bit.dsk SLTON.BIN assembled from slton.asm with lwasm with a listing in slton.lst This program appears on page 278 of the Assembly Language Programming for the Color Computer (1985) (Laurence A Tepolt).pdf file. Block at $4000 (16384) of length $003A ( 58): end at $403A BIN file length: $0044 ( 68) Entry point : $4000 (16384) Content length : $003A ( 58) Overhead : 17.2 % Single continuous block goes from $4000 (16384) to $403A (16442) P25.BIN: assembled from P25.ASM with lwasm with a listing in P25.lst this program appears as program 25 in the 6809_ch14_15.pdf file. Block at $3E00 (15872) of length $0124 ( 292): end at $3F24 BIN file length: $012E ( 302) Entry point : $3E00 (15872) Content length : $0124 ( 292) Overhead : 3.4 % Single continuous block goes from $3E00 (15872) to $3F24 (16164) On MAME these two programs are totally silent. On XRoar and a real Coco 2 they both produce sound. I think somehow the 1bit dac is not being routed properly somehow." | ||||
| 再現手順 | Mount 1bitsound.dsk LOADM "SLTON.BIN" EXEC ... or ...or LOADM"P25.BIN" EXEC You will not hear any audio. You will on a real Coco. | ||||
