 pokemini - ポケモンミニ | ||||
| 概 要 | DIV命令の約数が0のとき、CPUは例外を発生させるべき。 | ||||
| 詳 細 | The instruction DIV HL/A (CE D9) will crash MAME if A is zero. According to the information at https://www.pokemon-mini.net/documentation/minx-cpu/ , the CPU should hard-lock instead. That doesn't mean that MAME should stop responding, just that the CPU should no longer advance through the program. ~~~~~~~ MAME crash was fixed, but no divide by 0 exception handling | ||||
| 再現手順 | The program that causes this issue is attached. C:\MAME>mame pokemini -cart e:\data intendo\pokemini\ok\3dcubetest.min | ||||
