Hope this answers to few claims we got after releasing z88dk v1.10
cpp is reverted to its previous state to avoid conflicts with the inline assembler and a couple of minor corrections is inserted in the ZX/MTX relative libraries too.
You might be interested in the fixed/improved adv_a and dstar demos as well ..note that for the ZX81 there are 2 valid dstar versions: the common one (featuring graphics) and the 'text/udg' one, in the {z88dk/}examples/zx81 folder (press number keys to switch and find your correct UDG MOD, or rebuild the program with the proper parameters for DK'tronics or simple text modes).
adv_a is.. well a great piece of history. Its original version ran in FAST mode to be compatible with the expanded ZX80 (8K ROM), now it can be seen in Upper/Lowercase if an HRG mod is in place and it could be also possible to see pictures ! It is only a matter of free space, it runs fine on the Spectrum and I'm quite sure there is a way to see it working on a modified and/or expanded ZX81.
