Quick loading without an IRQ-loader!

Hey guys!

I know my ways around the various IRQ-loaders normally used today, but what about the non-IRQ-loaders (no music, $d011=0, sei, no-NMIs)?

- Which one can you recommend?

- Are there any that comes with source so that I can easily relocate them?

- How much faster are (can) a non-IRQ-loader be compared to an IRQ-loader?

- Any that perhaps easily can be connected to pucrunch or exo and thus load and decrunch at the same time?

- Is this stupid? Are the modern IRQ-loaders as fast or faster than the old legacy non-IRQ-loaders anyway?

things you should ask yourself:

- am I gonna use only that kernel loader or will I use an irq loader later on that breaks compatibility with those mcc/ide64 lamers anyway?

- is the speed gain really that much?

- some cartridge loaders are plain suckage (ie: unable to load under rom, slow and fiddle with more registers that could possibly break your program)

imho using a kernel loader should be an option, not a fixed feature.

Never seen a cartridge loader which cannot load under ROM. But most cartridge loaders cannot load below I/O area, just like the kernal loader.
