MagicEngine

[ETJ]

こんにちは

MagicEngineの現行バージョンにおいて物理的に危険なバグがありましたのでご報告を。
特定のゲーム（ここでは"アルナムの牙"を例とします）において
CDDA/PSGの切り替え時に以下のような症状が起こります、

CD再生を一時停止->PSG再生->CD再生->CD再生を一時停止,この時に
CD再生部分がおかしくなり短い区間をリピート再生し続けてしまいます。
ログでは次のようになっています

play audio 224763...224766
play audio 224763...224766
play audio 224763...224766
pause audio... OK

延々とCDへの細かなアクセスが繰り返されゲーム自体はコマ送り状態となり
CDドライブに膨大な負荷がかかり大変危険な状態になります
他のCDDAへ切り替わると（例：洞窟から地上へ出て再生する曲が変わると）と直ります
この症状は100%再現されます（当然ゲームCD自体には傷等はありません）
PC-Engine実機(DUO-R)では正常に動作し他のエミュレータ（YAME）でも正常です

長時間続けるとCDドライブが破損する危険があるので早めの修正をお願いしたいです

Wizardry I-IIでの似たような書き込みもありましたが
この場合と同様な危険性があるのか解らないため書き込みしました
それでは失礼します

私はこの問題について知らなかった。
解決を捜す。
システムカードROMを使用したまたはMagic Systemを使用したか?

Thank you for the reply!

Card to use is SystemCard 3.
Problem occurs in SystemCrad3.

This problem doesn't happen in MagicSystem. (Because there is no PSG)

I have found how to fix the problem.
I'm working on a patch right now.
