| 概 要 | ある条件でクロック速度が速すぎる。 | ||||
| 詳 細 | The emulated behavior of the SAM/VDG is incorrect in some circumstances. It affects NTSC/PAL machines for Coco 1, 2 and Dragons. | ||||
| 再現手順 | The following code will issue a double-speed POKE for the whole system: 10 POKE &HFFD9,1 20 GOTO 20 This will cause video screen corruption on a real Coco as the SAM/VDG can't keep up with the refresh rate. XRoar seems to emulate this correctly and you should see the following screen I've attached (screen corruption). The screen in MAME will remain unchanged and you will see the screen intact. | ||||
| 追加情報 | This issue was discovered while developing assembly code that utilizes the Spec & Sound cartridge. | ||||
