FLLOAD improved!

Nice, I’m sure I will refer back to that source code some time in the future .

Updated again !

fl_v131.zip

Fixed a bug of secondary slots. (thx to Fabf for the feedback)

I'm trying a Winbond W29C020-90 from a PC mainboard in my modified SCC cartridge (like the one on the WIKI here in the DIY section).
FL doesn't detect it, does it have to be an AMD chip?
I've tried an AM29F010-120PC too, without result.
Which ones are supported?

Thanks!
I never realized that other brand and type flashchips have a different way of flashing. I've ordered some AM29F040B from a Chinese shop... hopefully I'll actually get them

I use different methods. In general, you can find the Mapper type of a ROM file with an emulator or searching the bytes 32 00 XX with a binary editor. "LD (address), A" is often used to change the page. If this is not the case, I use an emulator specifically recompiled to indicate the value of PC register when a page changes.

We must also be attentif to the Slots status because when we change the mapper. The bank used to switch page may not contain ROM.

But above all I search if megarom has already been patched to compare it with the original. With a hex editor, it is easy and quick to note the locations to patch. If locations are many, I cut the file (8K or 16K) and I use a small Basic program that notes the data for me.

I also use a list of Mappers specifications and the BlueMSX debugger to check my job.

I can explain too the method used by FL.COM to patch on the fly if you want.
