PSPUAE 0.61 running SWOS - ADF vs RAM Installed Save-State (RISS)

This is a video i've posted up here to show what myself and FOL of www.pspuae.com have been doing to make the Amiga PSP emulator more playable.

What you see here, is a comparison between regular ADF loading, and the loading of a specially-created savestate, which has the entire game stored into the Amiga RAM.

I have timed from game load-start to the kick-off whistle of a first career game. you may notice an unneccessary wait on the titles screen, simply to demonrate the loading there. This adds about 35 seconds to the overall load time, which could be removed. It adds slightly more still to the ADF loading.

in case it's hard to read.. the times for loading were; 5:28 for the ADF loading, and 2:01 for the RAM savestate. When you consider that this extra time is being wasted all the time you are playing a career etc, or that on other games, disk-changes may also be necessary, it become very apparent that a lot of time is wasted with ADF loading, making it somewhat unsuitable for portable gaming.

The techniques we have used to eliminate the in-game loadtimes could probably be adapted for the GP2X as well. If anyone would like more info, get in touch on www.pspuae.com

a fresh cup of tea hehe :) great video

i would love this, im an amiga freak, this was in 2006? whats it like now on the PSP 3000/4000?

[HoraceAndTheSpider]

PSPUAE 0.72 as a whole is a lot faster, particularly with the FAME/C core (there are two flavours available) although that core is not as compatible.

I assume it runs the same on the 3000 using the 'HEN' loader, although, as i only have 1000 & 2000 i cant be 100% sure of that. (i suspect the only problem would be the loader eating memory)

4000/PSP-Go is not hacked yet is it?

[andy7666]

No, I'm still confused - is it much faster?

[HoraceAndTheSpider]

it's much faster LOADING.

this is also a very out of date version of PSPUAE on this video (it is almost 3 years old now)

there's a FAQ regarding RISS games on our website that will explain it much better than i can in a youtube comment reply!

Is hdf files supoorted? Like I see in latest

pspuae 0.72 a main Eboot.pbp file have in it

content "hdf" text, so why loading from adf?

It is take veeeryyy looong time to complete.

[HoraceAndTheSpider]

no, hdf isnt supported sadly. no author ever managed to successfully compile pspuae with the HDF functions of e-uae working.

and yes, adf is slow, which is why the faster method on this video was developed which uses RAM instead of ADF/HDF.

[andy7666]

Oh I see what you did you cheeky monkey - I do the same thing, just save a game at the menu/start of play and load from there! I was excited then - surely one day we will have a perfect Amiga emulator on the PSP..

[andy7666]

IsCould this be a new way to play PSPUAE then? Will they ever bring out a programme that you can choose the games from a menu and straight in, with authentic Amiga gameplay? I love the Amiga but all this slowdown just seems somewhat unecessary, surely? *Dont ask me to do it though!*

[HoraceAndTheSpider]

ECS. it's only 333 mhz processor, so it'll struggle with AGA (try running e-uae on a machine with a processor that low)

PSP resolution is 480x272, which is enough for the lowres modes used by most games. this kind of becomes irrelevant anyhow given PSPUAE's zoom features however.

[SaganAppreciationSoc]

What kind of graphics does the PSP UAE emulato support? OCS, ECS or AGA? ECS at least i hope- but what's the resolution of the PSP?
