Re: *** R-TYPE DELUXE SOURCE CODE ***

Okay I added stage select & cheat code activation when the game starts (from unpacked files right now) But I think there is already all the logic to go from on stage to another, there is a main part that loops back to the beginning of the level when you beat the boss (if the cheat mode is not ac...

Re: *** R-TYPE DELUXE SOURCE CODE ***

Thanx for this. I think that I need to do new release of it. Any tips for some further changes (nothing big) ? I'm going to check the game difficulty level, I'm not the best player at R-Type but I can go as far as Level 5 easily in the original game, and on this version I hardly succeed in ending t...

Re: *** R-TYPE DELUXE SOURCE CODE ***

Here's my fixed version (source code only):

- fixed syntax errors in the original source code
- removed the (useless?) lower border opening for the sync function

Now the game works for any CPU frequency, here's a capture on Mega STE running at 8 and 16Mhz:

Re: *** R-TYPE DELUXE SOURCE CODE ***

I would not agree with that. There is 2 kind of memory in Mega STE : regular ST RAM and cache RAM. If CPU addressing some address what is already in cache it will be accessed 2x faster than when is not in cache. You're right, 16Mhz on MegaSTE actually makes no sense when you don't enable the 16k as...

Re: *** R-TYPE DELUXE SOURCE CODE ***

Yes there some errors are misleading in devpac 3 when it comes to macros. I also found that there is bugs, at least in stage 1 the boss has graphic glitches. However I recommend to build this using vasm on another system, it takes about 2 seconds. Devpac takes a lot more time and when I switch Hatar...

Re: best LCD monitor working with ATARI SCART

I bought the upscaler (available for ~30€ on amazon) and it works, the picture quality is okay, but it applies a deinterlace filter to the atari input (!!!). So when you open a menu on the desktop, the picture flickers a bit before stabilizing. In addition there's some lag (maybe 2 or 3 frames). At ...

Re: *** R-TYPE DELUXE SOURCE CODE ***

Btw. Unroll is more efficient even with cache. Especially if we loop short code - because no dbf or other jumps to loop begin, which just eat CPU time, while doing nothing "useful" . Yes, there's the jump test time, but it all depends on the size of the loop itself, given that the cache a...

Re: *** R-TYPE DELUXE SOURCE CODE ***

Like in this block ? x set 0 rept 10 movem.l d0-d7/a2-a6,x(a0) x set x+(4*13) endr x is not a label, it's a macro variable defined to 0, then the block between REPT and ENDR is repeated 10 times. x is incremented by 4*13 between each REPT loop. That's because on ST it's more efficient to unroll loop...

Re: *** R-TYPE DELUXE SOURCE CODE ***

Has someone even tried to run this ? :) It doesn't assemble directly in Devpac, there's some typos in the source code. But after fixing two "(" missing and some REPT located on the same lines than labels (which devpac seems not to like), it works. Don't forget to ICE-unpack the levels with...

Re: ST and STE interlaced video signal

I don't have much experience with interlaced systems, but I'm not sure it would be correct. Let's say you have an horizontal line going down one scan line per field (50 or 60 fps). You display the line at scans 0,1 and 2. In a non interlaced system it appears at physical scan lines 0,2 and 4. But i...

Re: ST and STE interlaced video signal

Interesting topic :) I wondered if something interesting would surface with the ASIC designs now found. Well, just enabling interlace always and by default would break compatibility. Any kind of animation running at 50 (or 60) fps, won't display correctly. What were supposed to be two consecutive fr...

PS : I still have the ST Magazines with your articles, I even scanned/printed them to have them handy instead of keeping a pile of magazines. That was really great articles :cheers: So did I. I kept those magazines at hand during YEARS. At the time I was hanging with the folks of NGC, and when I sh...

Re: New to Atari STE need help

SCART with RGB inputs was mandatory in France on every TV set sold between 1981 and 2014.

As a result I know no example of any Atari computer of the ST/TT line that was sold with an RF modulator in France. They all were always provided with an RGB SCART cable.

Looks like something went wrong starting at ACC/Another_Brick_In_The_Wall: the songs after this one seem to be from the same sndh recording.

Thanks Leonard for the HDD & Mega STE version ! I will test it very soon :) I'm a bit sad I couldn't attend STNICCC and thank you in person (as for other things like SainT :p). Sad since I'm quite sure we already attended the same parties in the 90s. I agree that it's not important which way you...

Re: ATARI HDD low level info

Pardon my ignorance, but as far as I know by reading various documentations, if you do a low-level access to an HDD you need to support both the filesystem and the HW protocol used by the HDD. Granted ACSI & FAT16/FAT32 is the most used on ST and I guess you can code your own driver for that, bu...

Re: R-TYPE DELUXE

Ok, just tested on my Mega STE :) the patched version worked fine from UltraSatan, just as expected (I don't have a CosmoEx). I didn't know about the F1 menu and cheats so I couldn't reach the end of stage 1. Real autofire also helps 8) I must say this version is amazing, far better than the origina...

Re: R-TYPE DELUXE

I tested it on Hatari and Steem and it works fine, thanks a lot for the HDD patch. Note that with Hatari tha game crashes at 16Mhz but with Steem it runs fine at this speed, without slowdowns. Hopefully I will test it on my Mega STE@16Mhz soon ! However the game is really too hard, the collision mas...
