I'm kinda lost here. I've seen people recommend sourceports over the remaster, but I have also read somewhere that the sourceports were based on the leaked prototype source code and that OUWB on DOSbox or an actual DOS computer is the real way to play Blood.

I am only asking for opinions on what your preferences might be.

If you are new to Blood you will probably be fine just playing Blood: Fresh Supply. It is a little buggy, but most of the bugs are being addressed. Also if you are new to the game you wouldn't notice most of them anyway.

If I understand it correctly BloodGDX, originally referenced the early leaked alpha code, and a reverse engineered copy of Blood, but I don't know if M210 still uses it or if that has all been replaced with original code by the time he released his source-code for it.

NBlood is supposed to have been accomplished by a clean room design process. NukeYKT referenced some of the reverse engineering tools he used in the process, but the code he released to get it working with a (currently) forked version of eDuke, should have been independently generated. NBlood had some issues rendering rotating sectors earlier on, but I think those have all been addressed.

There are some differences between OUWB and NBlood and BloodGDX, but they are relatively minor. They can all play the Blood demo files and have them render the game-play out with very little, if any, variation. This is important because it actually renders a new instance of actual gameplay and they aren't actually video recordings. Think MIDI vs an MP3. B:FS can't play original demo files because they would render out completely differently. (The character would die too soon, or turn too much or miss targets entirely, etc.)

Playing BLOOD on an actual DOS computer may be problematic unless you can find a motherboard that still has PCI slots and you can get a SoundBlaster. You would still have to hexedit the blood.exe to not crash when you pick up the reflective shots or jump into water with a diving suit. (a bug with the PCI bus) You would also have to fix the cryptic.exe if you are running it on a [CPU faster than 200 MHz]

OUWB on DOSBox or some other emulation is probably a good if a little clunky long term solution.

B:FS will depend on how long they support it

NBlood, and BloodGDX will be around indefinitely since the source code has been released, but you can probably project out variants like Brutal Doom for Doom. Some people love it, some people hate it.

To be honest, I've gotten Blood back in 2016 on Steam, I think shortly before I made an account here, and kept it on my backlog until like a year or two ago, and I've used some guides to getting it to work and use the WASD configuration, but all of that was a pain.

Running Dosbox Blood was a pain, I got it years ago during a gog sale (as well as Blood 2 which i still cant get working properly to this day). Even after finding the optimal settings and configuration, the game still had some weird hiccups and performed poorly. BloodGDX and Fresh Supply, IMO, are both much better ways to play even if on very technical terms they aren't the original engine/enviroment. Being able to go straight into blood without booting bmouse or constantly changing my settings is great.

Like the guy who was first said it depends how long they support Fresh Supply. I suspect GDX may be better for custom content, but most things will work in Fresh Supply too now that they've fixed most things.

I've started playing blood with bloodGDX and I have still to play criptic passage. Is Blood: fresh supply worth to play with all these bugfixes done?

I did it backwards. I played Blood back when it was new and have played One Unit from here with DOSBOX. I bought Fresh Suplly, but they chose not to support my card, so currently it is useless to me.

Then I found Blood GDX. Honestly, if I had used Blood GDX in the first place, I would have skipped Fresh Supply.

I think Blodd is great as is and seems to work fine in DOSBOX for me. The only reason I'm interested in Fresh Supply or GDX is I want to use the mousewheel to switch weapons.

I would say yes it is. The mouselook in Fresh Supply is the best one the game ever had. BloodGDX and also NBlood can't compete at this point. Also the new 3D view and stuff like an fov slider are making the game a whole lot more enjoyable than it already was (and ever will be).

The game running in DOSBox has a pretty big issue, though, that being that the difficulty setting damage numbers flip on loading a save, so the only difficulty that actually works correctly is Lightly Broiled.

So you really are better off with Fresh Supply, GloodGDX or NBlood.
