Jetboot Jack

I've just got this latest version up running - awesome. Because I am awkward I tried under Big Sur, had to jump thru a few hoops, but eventually got it to boot 🙂 sTeVE

My shop from late 80's to early 90's... sTeVE

I saw Winter Games running on an XEGS at Atari UK in Slough, alongside UFO... Sadly I have no evidence of my experience (it was a way before camera phones) - and to be honest I was there to sign a contract for some software I was developing, little would I know the games I saw would never be released. sTeVE

Outstanding - really nice work! sTeVE

Very nice! Not having played/seen this game before is the burst scrolling part of the original product? sTeVE

That's very sad to hear, a real loss to the community... I really enjoyed Business Is Fun. sTeVE

I guess I am over dramatic 🙂 The original Genesis game is was so smooth and animation rich that every time play a lesser version I am always reminded what is missing. So for me the low frame rate, small enemies and visually indistinguishable scenery all makes it so meh on the GB... sTeVE

"PC original" - nope Genesis/Medgadrive original 🙂 Have you played the gameboy version OMG it's horrific, very little of the magic of EWJ left in that! sTeVE

Might as well start with a system closer to ours for comparison - look how crappy the Master System conversion was - and that machine is way more powerful (10Mhz custom Sega VDP) than an A8. It can put 64 hardware sprites on screen and addresses unto 4MB of cart space! sTeVE

I will go and have a look - being UK based I may have PAL memories 🙂 sTeVE

But they are all in mode 8 and so artifacted, not mode E 4 color (Ralf Bertenburg hack)... I wonder if that red is purple on XL/XE? sTeVE

I beg to differ - the Broderbund original is 100% colors by artifacting in the play area - it just has a black backdrop. There is a HACK that uses Antic E so you get a 160 horizontal resolution and 4 non artifacted colors on screen... sTeVE

So that's solved it - if I select Open GL or DX11 it works perfectly - thanks for the help... However if I have DX9 checked alone or combined with any other options - my system soft locks every time with 60HZ or NTSC video settings! sTeVE

Thanks for the suggestions phaeron - I will try the various options to see what happens! sTeVE

Thanks for the suggestion... I tried running Altirra from windows w/o my FE or CL options - booted to an NTSC 800 - loaded an xex (DK) - selected File/Exit and my system soft locked 😞 Now it does NOT lock up if I am in window mode when I exit, only exit from Full Screen causes the lock up. I get the same behaviour if I try 5200 games (which when loaded force NTSC) - File/Exit - locked up PC 😞 If I select Config System from the menu bar sometimes the FS switches to a window the the dialogue appears and sometimes the screen turns grey and the system is soft locked again. At this stage I understand it is my system, but where to start to look to fix it, I have no diagnostic information from the lock ups, I don't know where to look. I am running Windows 10 and I am on the insider program for updates... sTeVE
