Today I've uploaded A/NES v1.16b2, feel free to check it out. Some minor things has been fixed and one new feature has been added. It allows you to "simulate" the sound from the FDS diskdrive while running an FDS game. Insert a standard AmigaDOS floppy in your DF0: and activate the setting in the preferences section. Your Amiga diskdrive will simulate the read on your floppy to let you know when the FDS is actually reading.
Kind of useless, but fun perhaps? :)
Now for the sad news. This is most likely the end of A/NES. Due to lack of free time, lack of interest (hard to maintain these amounts of code) and due to lack of Amiga-users I've decided to put A/NES on ice from now on.
It's been fun but now it's over. Thanks for the feedback we've got during these years!

Don't worry, I'm still here.. :) I'm preparing a second beta release of v1.16 which I hope to release soon. Will contain some minor savestate fixes aswell as some new optimizations. Stay tuned!

Today I decided to upload a small beta of the upcoming version. I've implemented a small savestate-function. Try pressing F5 during play to create a savestate. By pressing F6, the game will load your savestate.
Could be usefull when you're tired of replaying the level because you died. Just beat a couple of enemies, do the savestate, beat some more, press F5 again etc. If you die, simply press F6 and the gameplay will resume from your last savepoint.
This feature is kind of experimental at the moment and may work better with some mappers than others, so be careful. Mapper1 & 4 are most likely to cause problems at the moment.

A/NES v1.1 is finally released! I'm pretty proud of this one since there are quite a few interesting changes. All of them are listed shortly in the included documentation but for those who are interested, I'll mention them more in detail here below.
Some changes (especially concerning sprites) may affect performance in a negative way on low-end systems (<=68030 CPU's). I highly recommend running A/NES on systems with atleast a 68040 or preferable a 68060 CPU.
Anyway, here's the changelist:
  • Audio improved - some parts of the audio engine has been rewritten and it should work better than previously. Especially "frequency sweeps" (Mario entering a pipe in SuperMarioBros) should sound pretty ok now.
  • 8x16 sprites bugfixed - Well nothing much to mention here really. 8x16 spritecode was earlier full of bugs and it should now work ok. An obvious example is Castlevania that looked terrible before and now looks alot better.
  • Mid-screen spritepattern-change supported. Some ROMs (Duck tales for example) using a different set of sprites depending on where the sprite is located on the screen. For example, the statusbar (In Ducktales) uses one spriteset and the playscreen is using another one. This didn't work earlier, now it does.
  • Minor graphicscode optimizations - well, a few fixes has been made.
  • Minor CPU-bugfixes
  • Improved CPU-timing - The 6502 emulator should now be even more accurate.

    A new website. It's quite simple but It'll do for now. :) I'll add more stuff later.
    Anyway, A/NES v1.1 is in the works and will be released shortly, stay tuned!
