While optional, the ability to use DMA is preferrable. Summary - UHS can do without dma. ;) I'd rather have it not. I'd -like- to be able to use ultimax mode, or at least a kernal cart. If that's not available, make a reasonable form of mem management if you have higher memory. A setup a-la scpu is acceptable, as UHS aims to load high and lower the top of mem pointer. Programs -assume- mem in bank 2, but they dont assume mem in the higher banks ;) Those that dont check and use the top of mem can suck me. -David Message was sent through the cbm-hackers mailing list
