Roland IRQ #63

Open kaloun34 opened 3 years ago

kaloun34 commented 3 years ago

Hello,

Many Dos games offer a configuration for the Roland ranging from irq 2 to 7. The Core ao486 requires it to be 9. Would it be possible to change it to 2 or be able to choose with an utility like the SoundBlaster?

2 is special IRQ. You can refer Wikipedia:

IRQ 2 – cascaded signals from IRQs 8–15 (any devices configured to use IRQ 2 will actually be using IRQ 9)
