A/NES PRO v1.11 released. Phew, this was alot of work. Anyway, here's the changelog:
* NMI/IRQ addresses in GUI was wrong. Fixed!
* Timing of branch-opcodes fixed! (Should now be 100% accurate)
* Improved CPU clockcycle timings.
* NES stack-related code rewritten, now behaves like the real hardware.
* CGFX/P96-driver should now be faster.
* Gameregion are now also detected by analyzing filename instead of only checking header.
* One-screen mirroring fixed (RC Pro Am is now playable)
* Mirroring fixes (Final Fantasy 1)
* Various mapper fixes
* Misc minor optimizations.

Just wanted to let you know I am working really hard with the next version. Currently I'm working to improve the timings. I dare to say that the NTSC mode is now probably like 90-95% cycle-accurate compared to a real NES. This means better compability in the end. Some games uses real ugly CPU-loops for scrolling ("Balloon Trip" mode in "Balloon Fight" comes to mind) and these kind of tricks will obviously work better with a more accurate CPU-core.

A/NES PRO v1.10 released. Some minor fixes was done, but the biggest news is CGFX/P96 support is now implemented! It's in an early state and is a work-in-progress but I hope it should work. :)
Remember that there's many hours of work developing A/NES PRO. If you want to support and encourage future development, feel free to use the Paypal-link found here.
Anyway, here's the complete changelog:
* CGFX/P96 support (partial, W.I.P)
* Spritehit flag for 8x16 sprites was sometimes ignored. Fixed (Zelda2).
* Fixed some scrolling issues.
* Shell-parameter handling was broken, fixed!

Time for a small experiment. How many of you are actually using A/NES or A/NES PRO? Everyone who send me an e-mail within the next 48 hours will get a preview version of the next A/NES PRO in their mailbox. The e-mail should contain a description of your Amiga setup (OS,RAM etc. etc.) + a short story about your A/NES experiences.
The e-mail address is here.

The work continues. I've fixed a few more bugs (Bubble Bobble now works 100%). I'm also trying to get MMC3 IRQ's to work properly. If you've tried SuperMario3 you can see the effect of no IRQ's running (statusbar is corrupt etc.). When enabling MMC3 IRQ's, things seems to crash and have a hard time locating the issue at the moment. Annoying to say atleast..

Today, thirteen years ago, A/NES was given birth. And today, it's time to announce the sequel of A/NES, entitled A/NES PROFESSIONAL.
This is the emulator that I've been working on the last couple of weeks and I think it's ready for a public release now. However, due to complexity of the NES, there's still a few bugs to fix.
Anyway, A/NES PRO, is for high-end Amigas. It's not something you want to try on your 68030. Minimum recommended setup is atleast a 50Mhz 68060 CPU (and overclocked is even better). The reason for these high requirements is that I wanted to create an accurate emulator. I am not there yet, but it's a start. :). A/NES PRO was inspired and designed with the NatAmi in mind.
Anyway, let's skip the tech-stuff, here's the news:
* Completely rewritten graphicsengine. Alot more accurate and nice looking, but also slower. :)
* Implemented "frameskip" option in preferences-section.
* ROMs can now be started from Shell, using "anes <romname.nes>".
* CPU-core bugfixes.
* Partial one-screen mirroring implemented (RC Pro Am)
* Mapper 87 implemented.

Parts of the new graphicsengine:
* Graphics are now handled as chunky- data instead of planar. More accurate at cost of performance.
* Sprite priorites implemented (sprites can appear behind background).
* CHR-bank swapping are now done entirely by using pointers instead of moving data. Many thousand percent faster than previous gfxengine.
* Screen-mirroring are now handled correctly and uses pointers instead of moving data (=alot faster). Games like Metroid and Zelda2 now works properly.
* Now uses C2P (Chunky2Planar) code by Mikael Kalms. Both 68060 and 68030 optimized versions included.

You may also have noticed that I've added a paypal-donate button my page. Feel free to use it if you'd like to encourage me to improve A/NES PRO even more in the future.
Now, check out the download-section. :)

More screenshots. These are actual screenshots from A/NES (grabbed by WinUAE). These games are fully playable in an upcoming A/NES release.

The gfxcoding was progressing nicely, until I discovered something that didn't quite work. So I have rewrite parts of the code (again) to make it work as I want to. This will hopefully result in even better compability.
I really want to release a public version soon so stay tuned. :)

2010-04-28
I've now changed my website provider to something that hopefully works a little better for me.

2010-04-20
Here are some more screenshots for you to enjoy!

The new gfxdrivers is progressing nicely. I hope to have a public beta available shortly. However, the new and improved gfxdriver is coming at a price, and that's performance.
Next version of A/NES will be targeted at high-end classic Amigas (040/060) as a primary goal, due to the increased complexity of the new gfxdriver.
However, I'll still do my best to continue to improve performance for all Amigas. But if you haven't overclocked your CPU yet, this might be a good time to do that. :-)

2010-04-06 update #2
I just thought it might be interesting to show some progress on the new gfxdriver. It's obviously not complete but anyway.. :)
Here's a quick screenshot of "RC Pro Am". Ignore the buggy colours. Worth to notice here is that the graphics is shown correct unlike current version of A/NES. This titlescreen features "midscreen patterntable-swapping" (for you technically interested), that A/NES currently doesn't support properly, but the new gfxdriver does!

Here's an early screenshot of SuperMarioBros (please ignore colours and buggy sprites). Those large gray blocks represents different "colour-layers" which isn't really visible during gameplay (assuming the palette is correct, which it isn't on this screenshot).
Anyway, the NES is a tricky piece of ancient hardware. :)
Oh by the way, at the moment the new gfxdriver *will* work on OCS/ECS chipsets. This is a feature once promised back in the 90's but perhaps it'll happen in the final release of the new gfxdriver (if ever finished). :)

2010-04-06
The work on the new gfxdriver is moving forward (slowly). My ambition is to make the gfxdriver work with A/NES as a plugin instead of integrated. And as usual, time will tell if this will succeed or not. It was along time ago I touched the gfxstuff in A/NES and at the moment I cannot say if the new driver will be usable on classic Amigas (which is of course, my goal). However, limitations of chipram and CPU makes this a challenging task. My current goal with A/NES is aswell to make it as accurate as possible (as accurate as the Amiga hardware allows). The downside is that making an accurate emulator requires fast hardware, and as you all know, Classic Amiga hardware isn't really up to date. :)
Some people may say that other NES emulators for AmigaOS can run some games at full speed on a 25Mhz 68030 or similar. Well, that might be the fact, but A/NES can't be compared to those emulators since they doesn't have any 6502 cyclecounting, which is a feature that improves compability but at the cost of performance.
Anyway, be sure to check back here for new updated versions of A/NES. Feel free to e-mail me if you want to show your support for A/NES. :-)

Working on a new gfxdriver (have just started..), time will tell if it'll end up useful or in the trashbin.

2010-03-30
The next version of A/NES is progressing nicely so if you haven't bookmarked this website, I suggest you do that. :-)

Miracles do happen. More than two years since last release and now A/NES has rised from the dead. :) Enjoy this new beta, "v1.17beta1". Development is now entirely done in WinUAE (sorry but it's the truth..).
The new beta has some palette issues fixes, a partly rewritten interrupt-handler for more accurate emulation. A NTSC/PAL mode is now available aswell. A/NES now detects the format of your ROMs and sets the current screenmode correctly (NTSC games now runs at 60Hz default and PAL at 50Hz). This is highly experimental so I hope it works on real Amigas. :)
Download it from the download-page. If you haven't installed A/NES previously, first install the v1.1 package and then replace the exe from the beta-archive.
I'd love to hear some constructive feedback so feel free to contact me!

2008-01-18
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!
